Abstract

A four-port shared radiator is proposed for 5.2 GHz wireless application using multiple-cut rectangular geometry and partially stepped ground. The difficulty in making the shared radiator structure is almost removed in the presented design, and without the help of any isolating structure, sufficient value of isolation is achieved. The proposed shared geometry produces isolation of >10 dB in the 4.96–5.5 GHz operating frequency band. The gain of the MIMO antenna varies from 2.4 to 5.5 dBi, and radiation efficiency is >63% in the proposed band. The ports are arranged in an orthogonal manner to reduce the mutual coupling. An envelope correlation coefficient is <0.03 in the proposed antenna band. The total active reflection coefficient bandwidth of the antenna is 500 MHz with best combination of input excitation angles of 90, 180°. The isolation in the proposed shared radiator is enhanced by creating multiple cuts and stepped ground. To check the suitability of antenna for indoor and outdoor environments the mean effective gain and specific absorption rate results are also presented in the paper and it found under the required safety norms as per the international telecommunication union for uniform and Gaussian environments.
