Abstract :
A novel loop antenna based on the volumetric folded ring resonator (FRR) structure is proposed. The FRR is embedded in a slotted ground plane for improved matching and radiation performance. Two bands, one at 3.6 GHz and another between 4.75 GHz to 5.8 GHz, are matched to better than S11= -10 dB and maintain a constant 2.5 dBi gain with >; 90% radiation efficiency. The simulated reflection coefficient and gain radiation patterns agree well with measurements.
