Description: Two elements diversity planar antenna for a
multiple-input multiple-output application is proposed. By adopting two Y-shaped radiators, the antenna provides wideband impedance
matching characteristic over the desired frequency band. To reduce the mutual coupling between two radiating elements, three stubs are
inserted in the ground plane. Good impedance matching and improved isolation characteristics are observed. The measured impedance bandwidth of the proposed antenna ranges from 2.27 GHz
to 10.2 GHz for return loss less than 10 dB. Parametric analysis has been conducted to investigate the effect of radiator length and
insertion of stubs on the impedance bandwidth and isolation characteristics.

Description: this code is to show how Matlab design works. I do not have the license of the code. This code can also be downloaded from files exchange.
The structure includes of a single ground plane and it is consequently low cost and simple to fabricate. It is found that isolation of more than 40dB can be achieved between two parallel microstrip patch antennas with using of one pair of slit two walls in air between microstrip antennas, inter-antenna spacing (center to center) is 0.257lambda_0. Also we are investigated that with different shapes of EBG on the walls we can reduce S12 more than 4 dB. At 0.94GHz it is shown that this translates into a center to center separation between antennas of just 20 mm. Similarly the structure can be applied to reduce mutual coupling between three or four radiating elements. A simulation result is used to confirm the suppression of mutual coupling between closely-packed antenna elements.
