Abstract :
Antenna for mobile terminal of satellite navigation GPS and/or communication e.g. IRIDIUM, GLOBALSTAR systems is proposed. The novel design presented here takes two semi-ring patches of different radii, fed by a single microstrip line via a crossed slots in the ground plane, to produce an antenna with a CP axial ratio < 3 dB, and different impedance bandwidth, depending on frequency of operation (1.76, 5.4, 9.2, 14.9, 17.3 GHz). Antenna dimensions are determined approximately as for annular-ring patch of the TM11 mode. The antenna can also be designed as a dual-band antenna with orthogonal linear polarisation.
