Ultra-Wideband MIMO Antenna with Double Notched Band

Abstract

This paper presents an ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna with a small size of 41×41×1.6mm3. Double notched bands are obtained by introducing C-shaped slot and L-shaped slot. The proposed antenna exhibits good UWB performance, it achieves impedance bandwidth from 3.1GHz to 10.8GHz, and better than -15dB of isolation over the entire operating band, with adaptable double band rejection to avoid interference caused by two narrow frequency bands WLAN (5.15-5.85 GHz) and X-band satellite communication systems (7.25-7.75 GHz).
