Abstract :
Performance of two 0.3 wavelengths separated antennas in the 700 MHz band are evaluated and improved by connecting a matching and decoupling network to the antenna ports. It is shown through simulations that the network improves efficiency, diversity gain, MIMO Shannon capacity, and reduces the correlation coefficient. The concept is implemented and validated in two dual-antenna mock-ups with slightly different ground plane sizes.
