Abstract
A compact ultra-wideband Multiple-Input-Multiple Output (MIMO) Monopole antenna is proposed for frequency-notched applications. The proposed MIMO antenna consists of two identical Monopole antennas excited by two microstrip feeds. A stub is attached to the ground plane to improve isolation and impedance bandwidth. A quarter wavelength spur line is embedded on the feeding part of the antenna to achieve the notch frequency. The designed antenna exhibits −10 dB impedance bandwidth, covering the entire UWB spectrum. The L-shaped spur line contributes to the notch frequency at 5.5 GHz aiming to avoid interference from 5 to 6 GHz WLAN band. The planned model is fabricated and described in terms of impedance and radiation constraint measurements, compliant with those of results achieved from full wave simulation.
