Abstract

In this paper, two simple electronically-steered on-board satellite-tracking circularly polarized stacked-type dual-band patch array antennas for mobile satellite communications are numerically investigated. The configurations of the novel antennas are shown and their performances are discussed. The first model is fed by probes while the second one is fed by microstrip line. The gain obtained for an elevation angle of 48 is 6.4 dBic at the receiving frequency and the gain is 5.7 dBic at the transmitting frequency for the former model. Additionally, the axial ratio at both frequencies is around 4 dB. Regarding the latter model, for the same elevation angle, the gain is 6.4 dBic for the transmission but only 3.3 dBic for the reception. However with this model the axial ratio is satisfactorily less than 3 dB.
