Abstract
A circular ring structure with a tapered feed monopole antenna is designed with size of 1.3 λ0 × 1.4 λ0 × 0.095 λ0 mm3 (L × B × H). The maximum reflection coefficient |S11| with the tapered feed is −36 dB, without tapered feed is −25.55 dB and peak gain is ≥ 5.0 dBi in both cases. Proposed antenna produces bandwidth of 1.25 GHz while allocated bandwidth for ISM-III band is 250 MHz. The obtained bandwidth is wider than the allocated bandwidth. Proposed antenna qualifying the obtained measured results. This antenna is applicable for 5G Communication, Radar, and satellite services with miniaturization feature.
