Linearly tapered slot/notch antenna (LTSA)

Image of the Linearly tapered slot antenna.

One of the most popular slot antennas (along with the Vivaldi and Constant-width slot), the LTSA provides good wide-band performance and is easy to construct and design compared to other slot tapers (though it may be marginally longer for the same bandwidth). If you need a basic slot antenna that can be arrayed, this may be the one for you!
