The basic U-slot shape usually adopted for enhancing the bandwidth response of a microstrip patch antenna is properly modified in this work to significantly reduce unwanted cross-polarization effects. A wideband impedance matching is obtained by introducing a proper anular gap around the feed probe, in order to compensate for the large inductive reactance due to the presence of a thick substrate. A compact P-band prototype with a 15% bandwidth is realized and experimentally tested.

Abstract
The basic U-slot shape usually adopted for enhancing the bandwidth response of a microstrip patch antenna is properly modified in this work to significantly reduce unwanted cross-polarization effects. A wideband impedance matching is obtained by introducing a proper anular gap around the feed probe, in order to compensate for the large inductive reactance due to the presence of a thick substrate. A compact P-band prototype with a 15% bandwidth is realized and experimentally tested.File in questo prodotto:
