MIMO Antenna Design for 5G Smartphone Application

There is vast research conducted on MIMO antennas, and MIMO 5G antenna are on high demand. Here, in this article, antenna for broadband is optimized for 5G smartphones. In this, an antenna featuring an inverted-T shaped slot is proposed and found that it operate with a bandwidth of 90%. Two such antennas are then combined into one 2× 2 sub-MIMO array that can offer similar broadband characteristics as the single element while displaying greater than 10dB isolation between elements. Finally, such pairs of antenna are assembled in a 12× 12 MIMO configuration capable of covering frequency bands of wideband bandwidth. The performance results from simulations and measurements are included to support the working of the layout.
