Abstract

The paper presents, a compact planar two-element ultrawideband (UWB) multiple-input and multiple-output (MIMO) antenna. The work constitutes a half-circle shape radiating and lowered ground plane monopole antenna. The total area of the UWB MIMO antenna is 13.5 × 30 × 1.6 mm3. The proposed structure has an impedance bandwidth of 150% (1.6 - 11.4 GHz) in simulation and about 145% (1.8 - 11.3 GHz) in measurement and average isolation better than 30 dB in the UWB range. Various diversity parameters are also evaluated as described below. Envelope correlation coefficient (ECC) is less than 0.001, diversity gain (DG) is more than 9.9, mean effective gain (MEG) below - 6 dB, channel capacity loss (CCL) less than 0.2 bps/Hz, total active reflection coefficient (TARC) less than -10 dB, and multiplexing efficiency less than zero over an operating frequency band. The time-domain analysis is carried out, particularly group delay and fidelity factor. The results of time-domain analysis guarantee that the output pulses are less sensitive to interference.
