Small CP Cavity-Backed Magneto-Electric Antenna with parasitic elements for GNSS Applications

In this paper a small dual-band cavity-backed magnetoelectric (ME) antenna is proposed. This antenna is circularly polarized (CP) and designed to operate in all GNSS bands (1.164 - 1.30 GHz and 1.559 - 1.61GHz). Parasitic elements are added to create additional resonance. It exhibits axial ratio (AR) <; 1.3dB in all the considered bands and small external dimensions of 90x90x37.5 mm

(0.346x0.346x0.144 λ

at lowest frequency). It also provides a regular broadside gain of 5.2 dBic.
