| Abstract: | A broadband personal communication system (PCS) antenna concept, based on a low cost stacked patch approach is presented. The manufactured single element shows an insertion loss bandwidth (-14 dB) of 15.9% and is dedicated to the established PCS 1800 system including the DECT frequencies. The base station array antenna, a 1×8 element column array, is fabricated using dual ±45° polarised single elements. Within the 13.9% bandwidth of the array (-14 dB) the measured level of cross-polarisation is below -16.5 dB over all angles in both principal planes |
