Zusammenfassung: | Provided is experimental verification that a textured surface slot antenna is capable of producing usable far-field radiation patterns with preferential radiation into the forward half-space, at better than -16dB return loss. In addition, it is shown that the antenna when connected to a 50 load yields a backscattered return of only -17dB compared to a matched slot antenna constructed on a perfectly conducting (PEC) ground plane, which returns -3dB. The gain of the textured slot antenna structure was measured to be 3.35dBi at 4.77GHz. |
