A compact microstrip line fed wide band MIMO antenna with high isolation, dual notch bands with high gain and low correlation coefficient is proposed in this article. These characteristics makes antenna superior for diversity applications. U‐shape slots are etched on radiating element and on feed line to achieve decent band rejection capability. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1222–1226, 2017

A planar six‐elements, dual‐polarized, high‐gain, multiband antenna for diverse application is proposed in this manuscript. The proposed design consists of six radiating elements and a parasitic element on the top side of the structure. Each radiating element consists of overlapped ellipse with a line feeding technique. Iterations have been carried out on the number of antenna elements as well as on the spacing between the elements to get a minimum coupling between antenna elements. To compensate the coupling effect as well as to increase the impedance bandwidth, a ground plane structure has been modified with “L” shape structures. Fabricated prototype has an isolation less than −2 dB with highest gain of 6.7 dBi. Diversity in polarization is achieved by orienting antenna elements in vertical as well as in horizontal directions. A simple and compact design of antenna with good gain and less correlation coefficient makes an antenna useful for multiple input multiple output (MIMO) applications in the wireless communication systems. Simulation and measurement results validates the use of proposed structure in various applications like ISM, WLAN, Wi‐Fi, short range radar, and satellite applications.
