Abstract: | A probe-fed patch antenna that generates low cross-polarised radiated fields is presented. The probe is located in the centre of the patch conductor and a microstrip line within the patch is used to ensure that good impedance matching is achieved. Enhanced radiation performance of the printed antenna is demonstrated by theoretically and experimentally investigating a circularly polarised (CP) version of the probe-fed patch antenna and comparing the results with a conventional probe-fed CP patch. The new radiator has an axial ratio of less than 1.5 dB at broadside and a 3 dB axial ratio beamwidth of close to 200deg |
