Small Conformal Cavity-Backed Magnetoelectric Antenna for GNSS Bands

International audienceIn this paper a linearly polarized cylindrically conformal cavity-backed magnetoelectric (ME) antenna is presented. This antenna has a wideband behavior (S-11 < -10 dB from 1.15 to 1.68 GHz) which covers all the GNSS bands and a small size of 75x75x40 mm(3) (0.285x0.285x0.15 lambda(3) at lowest frequency). It also provides very steady radiation properties with gain of approximately 5 dBi and 3dB Beamwidth over 100 degrees 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
