Abstract

A single-fed right-handed circularly polarized (RHCP) dielectric resonator antenna (DRA) with in-band filtering for Global Navigation Satellite Systems (GNSS) application is proposed. The design is implemented by placing rectangular DR material above feeding slots through which, two sets of degenerate orthogonal modes, the TE111 and higher order TE112 mode, are simultaneously excited to achieve circular polarization. The proposed antenna employed simplified structure and feed network to filter antenna radiation between 1.30 and 1.5 GHz to reject in-band interference from L-band satellite and terrestrial communication signals. An antenna prototype is fabricated and tested to validate performance of proposed design with a total antenna size of 103×87.5×50mm3. The measured -10 dB impedance and axial ratio bandwidth are approximately 11.03% (1.164 - 1.3 GHz) and 3.21% (1.559-1.61 GHz) in lower and higher band of GNSS respectively. The gain is found to be of 4 dBi within passband with maximum value of 5.5 dBi at 1.56 GHz.
