Wideband High Gain Antenna Realized From Simple Unloaded Single Patch.

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 \textS11 \leq 10\,\text{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\,\textmm \times 13\,\textmm patch folded to realize 13\,\textmm \times 13\,\textmm footprint.
