  • Abstract
    In this paper, a new approach of port isolation for UWB MIMO antennas is investigated through active integration with a power amplifier (PA). Instead of 50Ω based design, a co-design approach based on the complex impedance of the PA and the antenna is adopted for better MIMO antenna matching and port isolation. Such approach does not require extra decoupling networks. The integrated antenna system covers 1.5-6GHz and shows minimum port isolation improvement of 5.5dB. The minimum efficiency and highest envelop correlation coefficient are found to be 62% and 0.115 respectively over the band 1.5-6GHz.
