A UWB-X Band With Three Notched Filters Inheriting High Isolation 2�2 MIMO Antenna Designed for High Speed Wireless Applications

Abstract

Hexagonal shape placed two radiating elements with common ground is proposed for UWB 3.10GHz-10.60GHz -X 8.00GHz-12.00GHz band wireless applications. Isolation between the two ports is achieved by placing pair of L-type stubs in ground. Triinterference bandwidth (W1MAX 3.0GHz-3.80GHz , WLAN 5.150GHz-5.825GHz & Downlink Satellite System 7.25GHz-7.75GHz ) is removed by introduction of stop-band filters in the form of C-type slots and inverted T-type stubs on the patch. Designed antenna is characterized by studying diversity performance which includes results like ECC 2�2 (Envelope Correlation Coeffieient 2�2 ), DG 2�2 (Directive Gain 2�2 ) and TARC 2�2 (Total Effective Reflection Coeffieient 2�2 ).
