A polarization diversity microstrip antenna with 45 dB isolation using insert rectangular slot is presented in this paper. The design procedure and the electrical characteristics of the proposed antenna are discussed. Furthermore, the adaptive polarized antenna system by using the proposed antenna as the radiating element is investigated and rf circuits for adaptive polarized antenna consists active power divider, control status switch, rf switch respectively. The measured results found to be the same as simulation results.
