Tuning Fork-Shaped Textile MIMO Antenna for UWB Applications

In this paper design a multiple-input multiple-output (MIMO) antenna for ultra-wideband (UWB) application, which is small in size, and having good isolation between its two ports, is presented. The MIMO geometry being demonstrated is made up of two similar antenna configuration and a microstrip line is used for exciting the wave. Since the elements are arranged perpendicularly, isolation between antenna ports can be achieved without the use of additional decoupling design. As a result, over the whole operating frequency, 32 dB of minimum isolation between ports is obtained. The given antenna has dimensions of 56 mm by 24 mm by 1 mm, and its frequency band extends from 3.1 GHz to 10 GHz (6.9 GHz), with a fractional bandwidth of 105.34%. This possibility for wireless UWB applications is demonstrated by the performance of the presented UWB textile MIMO antenna.
