Development of Diagonally Positioned MIMO Antenna with Improved Isolation and ReS Mitigation for Multiband Uses

Abstract

MIMO boosts wireless data speed. MIMO reduces fading. MIMO antennas increase channel, spatial, and pattern variation. MIMO uses multipath transmission since several antennas share a band with diagonally isolated orthogonal antenna elements. PIN diodes boost S (2–4 GHz), C (4–8 GHz), and X (8–12 GHz) band gain, bandwidth, and efficiency. The final section shows a multiband MIMO antenna with low RCS and good radiation performance, Wi-Fi (2.45 GHz), WiMAX (5.2 GHz), LTE (2.4 and 5.1 GHz), and military applications are compared with the measured and modelled outcomes. Keywords: MIMO (Multiple Input Multiple Output) antennas, RCS (Rich Communication Services) characteristics, Wi-Fi (Wireless Fidelity), WiMAX (Wireless Inter-operability for Microwave Access), LTE (Long-Term Evolution).
