Description
Summary:A slot-coupled stacked patch antenna operating at 35GHz with dual-polarized operations is presented in this paper. To achieve wide bandwidth and high gain at 35GHz, four parasitic patches are located above the active element. The measured results show that the frequency bandwidth of S 11 less than -10dB covers 30-40GHz and the isolation between two polarization ports is higher than 20dB at the center frequency of 35GHz. The peak gain at is 9dBi. Both theoretical and experimental results of reflection coefficient, isolation, and radiation patterns are presented and discussed.
