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

摘要

Hexagonal shape placed two radiating elements with common ground is proposed for UWB3.10GHz-10.60GHz-X8.00GHz-12.00GHz band wireless applications. Isolation between the two ports is achieved by placing pair of L-type stubs in ground. Triinterference bandwidth (W1MAX3.0GHz-3.80GHz, WLAN5.150GHz-5.825GHz & Downlink Satellite System7.25GHz-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 ECC2×2 (Envelope Correlation Coeffieient2×2), DG2×2 (Directive Gain2×2) and TARC2×2 (Total Effective Reflection Coeffieient2×2). Designed antenna offers wider-matched bandwidth of 2.53GHz-12.68GHz.
