• Two additional design groups have been added to the resonant series-fed patch antenna. These design options allow for more flexibility in the choice of excitation distribution that is designed for.
• Previously, licence files for purchased perpetual licences of Antenna Magus were created to expire every 6 months, at which point a new licence file would be retrieved from the Antenna Magus licence server (this would happen automatically in the background where an internet connection is available). The expiry period has been extended to 1 year so that users that do not have internet access and require manually-generated licence files only need to receive a new licence file once per year.
• The Array synthesis tool has been extended to allow for the consideration of reflecting ground planes in the pattern calculation. The ground planes may be parallel to any of the principle planes and offset by an arbitrary distance.

• In some cases, when estimating the performance of the rectangular cavity backed spiral, the gain vs frequency performance may not have been shown. This has been corrected.
• When entering a new substrate definition into the substrate library, the displayed limits for relative permittivity were incorrect. This may have caused some confusion and has been corrected.
• When tweaking the values of designed offset-fed reflector antennas, an out-of-range error may have been incorrectly displayed for negative offset angles. This has been corrected.
• When starting up Antenna Magus, the splash-screen may have appeared on top of all windows and not moved to the background when shifting focus to another application. This has been improved.
• When tweaking designed values of variables of the Potter Horn while in Export Mode, an exception may have been triggered due to an error in a message. This has been corrected.
• When designing a Conical Corrugated Axial Choke Lens Horn, an information message indicating the 10dB beamwidth assumed for the design may have shown an incorrect value. This has been corrected.

Data and report exporting

• Generation of a comprehensive antenna design and analysis report in MS PowerPoint format.
• Exporting of graph data to tab-separated-value files.
• Generate pdf file of Antenna information documents and articles.

Overhaul of substrate library and substrate usage mechanism

• Properties of the substrate to be used for an antenna design may be directly specified in the design pallet (without first specifying the required substrate in the substrate library).
• A 'Recently used substrates' list has been added that can be accessed from the design palette.
• A short-cut to the Substrate library is available in the design palette where any substrate is used.
• Substrates added in the design pallet can be added to the substrate library shortlist directly from the design palette.
• When the substrate library is launched from the design palette, a substrate can be selected and used in the design using the 'Use substrate' button.
• A display filter based on values of substrate properties has been added to aid searching for specific substrates. A tolerance is included for all values.

Information Browser extension and improvement

• A special side-by-side comparison option has been added to allow 2 antenna information documents to be viewed in a side-by-side layout. The corresponding sections of the information document are aligned to aid comparison.
• Antenna Magus Help files and articles on antenna-related topics can be accessed from the Info Browser Home page.
• The scrollbar position of each active document or comparison in the Info Browser is remembered and maintained when switching between items.
• A Quick-access home page has been added to the Info Browser.
• Title-bars added to documents that are being viewed in the Info Browser.
• The list of documents shown in the Info Browser is decoupled from the Antenna Magus collection content. Documents can be added to the Info Browser from the Home page, by clicking on the 'Info' button on an antenna thumbnail in the Find mode or using the 'Add to Info Browser' button in the Ribbon.
• The 'Info' button on antenna thumbnails in the Find mode only adds the information document to the Info Browser, but does not launch Info Browser window.

Antenna improvements and changes

• Internal analysis speed improved for the Elliptical pin fed circular polarised patch.
• Solid Bicone design for "optimal size" larger than design for "optimal performance". This design has been improved.
• For some cases, performance estimation for the Dual microstrip-edge-fed patch and Folded dipole antenna may have been incorrectly disabled.
• Some error messages for the rectangular edge-fed patch and circular EM-coupled patch designs have been corrected.
• When designing a rectangular stacked patch antenna, S11 was always plotted in a 50 Ohm system, even when the design was for 75 Ohm. The correct impedance is now used.
• The model notes in biquad antenna export models now discuss the use of symmetry.
• When exporting a Wire discone model, the upper limits on the parameter values was not correctly applied. This may have resulted in incorrect models.
• When estimating the performance of the Horn-fed Cassegrain antenna an error may have occurred for certain parameter sets. This has now been addressed.
• When designing a printed LPDA antenna, the objective ranges were not correctly applied.

Additional, general features and improvements

• When viewing 3D antenna images, 3D patterns and 3D pattern layout, interactive 3D rotation of the display using the mouse is possible (this replaces the pre-defined animations in the 3D view).
• An 'Export and Open' Model button has been added in the Export Mode, to save and launch a model in CST CST Studio Suite or FEKO^® directly.
• The reference impedance used to calculate VSWR or Reflection coefficient can be modified independently for each design or tweak in the indicator graph of the zoomed view or impedance vs frequency charts.
• Antenna Magus periodically creates automatic backups to avoid loss of information in the event of a system failure or power loss. When the system is restored and Antenna Magus reopened, the last state of all work will be restored.
• A information pop-up on collection items indicates when an internal analysis for that item has been completed.
• Antennas and array items in the collection may be reordered.
• If an item is removed from the collection, Antenna Magus asks for confirmation before deleting the item if the item contains computed design or estimation information.
• When closing Antenna Magus, any currently running tasks are listed, allowing the user to cancel the close, wait until all tasks are completed or force Antenna Magus to abort the tasks before closing Antenna Magus.
• Various additional models made available for CST Studio Suite^® and FEKO^®.
• When in find mode, pressing 'enter' adds the selected antenna to the collection and switches to design mode.
• Double-clicking on a 3D chart, 3D pattern view or 3D array layout view in tiled view switched to Single View mode. When in Single view mode, double clicking switches the view back to tiled mode.
• Sliders do not use nudge increments, but jump to the clicked position on the slider.
• The layout and navigation in the keyword list in the find mode has been improved. Up/Down arrows are supported.
• A 'Reset zoom' button has been added when zoomed to a section of a chart in Single-view, to revert to the default zoom level.
• The licensing and installation mechanism has been improved and made more robust.
• The management of antennas, designs and tweaks for long user-assigned names has been improved.
• The name of each design and tweak is shown in the header of the chart indicator tables along with the color block indicators.
• Line-style legends have been added to charts to aid in differentiation where multiple traces are shown for one design (e.g. where E-plane and H-plane pattern cuts are shown on the same chart).
• Antenna Information document and keyword consistency has been improved (specifically with a view to simplifying document comparison and tag-based searching).
• The 'Handedness' of coil or helix structures is more correctly handled in relevant antennas.
• The tab ordering has been improved in many places.
• The general performance of Antenna Magus has been improved. Of particular importance is performance at startup and when updating search results in the find mode.
• Busy indicators have been added during some tasks that typically may take a few minutes.
• When in Design mode, the Designs and Tweaks list is always visible.
• Color blocks assigned to specific designs and tweaks are not shown until a performance estimation has been completed.
• Derived quantities show complete descriptions in tooltips when hovering over them with the mouse pointer.
• When in Find mode, the search results list may be navigated using up/down arrows, page up/down or by scrolling with the mouse scroll wheel (previously scrolling was not possible when the mouse cursor was located over the antenna thumbnails list).
• The choice of Cartesian/Polar display for quantities plotted against angle is applied to all representations in the selected chart (previously each representation view had to be switched separately.
• Under certain circumstances, charts may have been out of sync with visibility and format settings. This has been improved.
