Eight-Port MIMO WiMAX/XSS Antenna Printed on Thin-Substrate for Multiple-Wireless Applications in WiMAX-X Band Satellite System

In this communication, eight-port MIMO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">WiMAX/XSS</inf> antenna with applications in WiMAX and X-Band Satellite System (XSS) is reported. The radiating-patch is modified square-patch with bottom chamfered-edges which is fed-asymmetrically by defected-microstrip-structure (DMS). The ground is partial-rectangular with open rectangular etched slot placed beneath fedline. The antenna configuration is printed on Rogers-thin substrate with thickness 0.252mm and is fed by modeled SMK-connector. The MIMO antenna offers isolation of more than 10.0dB with two bandwidth corresponding to Band1=3.44GHz-3.59GHz and Band2=6.89GHz-10.55GHz.
