Printed folded dipole

The planar folded dipole is a simple structure that can be etched onto the same substrate as electronic components. The antenna provides higher bandwidth and impedance than a simple planar dipole.

This type of antenna is popular in mass-production electronics where a simple integrated antenna is required. Though, strictly speaking, a balun should strictly be used, the coplanar strips input of the antenna may be connected directly to a differential drive or input with minimal effect on performance.
