Abstract :
A wideband antenna has been conceived and realized from a single metallic patch with air as the substrate. The patch has been strategically folded to achieve dual resonances resulting in S11 ≤ 10 dB over a wide matching bandwidth. Basic design concept has been discussed and experimentally verified. As much as 26% bandwidth covering almost the full X-band with about 9.6 dBi peak gain has been experimentally demonstrated from a 20.3 mm × 13 mm patch folded to realize 13 mm × 13 mm footprint.
