Small Conformal Cavity-Backed Magnetoelectric Antenna for GNSS Bands

In this paper a linearly polarized cylindrically conformal cavity-backed magnetoelectric (ME) antenna is presented. This antenna has a wideband behavior (S11 < −10 dB from 1.15 to 1.68 GHz) which covers all the GNSS bands and a small size of 75×75×40 mm
³
(0.285×0.285×0.15 λ
³
at lowest frequency). It also provides very steady radiation properties with gain of approximately 5 dBi and 3dB Beamwidth over 100°for all GNSS band and for both E and H planes of the antenna. A prototype was fabricated and a good agreement is found between measure and simulation.
