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

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 ). Designed antenna offers wider-matched bandwidth of 2.53GHz-12.68GHz.
