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.
