Textile UWB MIMO Antenna for Wireless Applications

An ultra-wideband (UWB) compact size with high isolation two-port “multiple-input multiple-output (MIMO) antenna” is proposed. The presented MIMO geometry is made of two monopole antenna elements and a microstrip feed-line use. The elements are placed perpendicularly and due to this, isolation between antenna ports is attained without using any extra decoupling architecture. Thus, the minimum isolation between ports is 25 dB obtained in the entire operating frequency. The size of the presented antenna is 58 x 25 x 1 mm
³
and the frequency band (S
11
< -10 dB) is covered from 3.4 GHz to 11.5 GHz (8.1 GHz) and fractional bandwidth is 108.72%. The result of the presented UWB textile MIMO antenna shows that option for C-band applications.
