Abstract: In this study, we are presenting U slot notch band MIMO antenna with polarization diversity technique. Polarization diversity is achieved by placing two pairs of monopoles orthogonal to one another. We used octagonal shaped slot antenna and differential feeding mechanism. We inserted slots which are in the shape of arcs to reject the Wireless Local Area Network (WLAN) band. For effective rejection of required band we inserted U shaped slots in feeding lines of port 3 and 4. The same can be done on port 1 and 2 as a result the parameters related to port 1 and 2 will be effected but port 3 and port 4 parameters are effected in this because the insertion is on port 3 and 4. The proposed model is achieving differential reflection coefficient of >-10dB over the rejection from 5 and 6 GHz. Due to differential feeding mechanism low cross polarization and port to port isolation of higher than 40dB is obtained in working range of antenna. Though the antenna is designed over 3-11 GHz, this is well suited for 6-9 GHz.
