摘要：

A compact and novel star shaped fractal microstrip patch conformal MIMO antenna suitable for WLAN, vehicular communications (5.855–5.925 GHz), and Fixed Satellite Services (FSS) applications is proposed in this paper. The analysis of planar and conformal single element and four element MIMO antennas is presented. The proposed star shaped fractal MIMO antenna is prototyped on a polyamide substrate of geometry 104 × 30 × 0.4 mm3. It achieves an impedance bandwidth (S11 < −10 dB) of 3.7 GHz operating from 4.53–7.86 GHz. Radiation patterns and surface current distribution are investigated at 5.9 GHz and 7.3 GHz center frequencies. Peak gains of 5.42 dB and 4.86 dB are obtained at 5.9 GHz and 7.3 GHz, respectively. Radiation efficiency is more than 98%, and MIMO performance parameters are also analyzed. The proposed conformal MIMO antenna shows fine diversity performance for WLAN, vehicular and FSS communications. © 2023, Electromagnetics Academy. All rights reserved.
