Abstract

A single-feed wideband circularly polarized Spidron fractal slot antenna with a grooved dielectric resonator is presented. To realize a wideband axial ratio, the circular polarizations of both a Spidron fractal slot and a grooved rectangular dielectric resonator are merged. The proposed antenna is excited by a simple 50-Ω microstrip feed line which is located underneath the Spidron fractal slot. A prototype of the proposed antenna is fabricated and tested. The measured −10 dB reflection coefficient bandwidth and 3 dB axial ratio bandwidth are 40.33% (1.94–2.92 GHz) and 23.75% (2.30–2.92 GHz), respectively. The measured peak gain of the antenna is 4.23 dBic.
