A UWB MIMO antenna with dual-polarization and high port isolation is proposed with simulation and measurement included in this paper. The antenna shows good performances in reflection coefficient and high isolation with S21 <; 20dB in the entire UWB band. The radiation patterns show fairly constant pattern stability in aperture mode port and some variation observed for the slotline mode. The orthogonal...
A 4-port antenna is designed for evaluating the performance of an MIMO system in indoor environment. Diversity gain, correlation coefficient and channel capacity are calculated and discussed in this paper. The selection diversity becomes more unapparent when using more antennas in MIMO system. Correlation in both rich scattering and high K-factor environment are found below 0.2 and 0.5 respectively...
