A wideband T-shaped slot antenna and its MIMO application

A wideband slot antenna and its MIMO application is presented. Both of them have a very simple structure. The single antenna merely consists of a T-shaped slot while the MIMO antenna has two T-shaped slots and two slits, which are used to improve port-to-port isolation. Simulated results show that the single antenna achieves an 83.3% impedance bandwidth with |S₁₁|<;-10 dB from 1.4 to 3.4 GHz and a 47% impedance bandwidth (1.95-3.15 GHz) is obtained for the MIMO antenna with a port-to-port isolation greater than 16 dB. The antennas should be a good candidate for wideband wireless communication systems.
