摘要

In this research paper, an optimized 2 × 2 MIMO UWB antenna (antenna-E)with half circled radiators as well as 50 Ω step fed has been introduced. Theproposed UWB MIMO antenna has been evolved from recent peer publishedpapers that provide WLAN notch (5.15-5.85GHz), ultra wide band width(3.1-10.6 GHz) and again a very good isolation (−20 dB) also maintained. Inthis paper the evolutions have been derived from antenna-A to antenna-E. TheUltra wide band is achieved by using step feed line, cutting a metal strip on apartial ground plane, a rectangular slot underneath the feed line of each radiatorin antenna-E. A high isolation (−20 dB) is obtained by introducing twoinverted Г shaped stubs in the ground plane. Both antenna-D and antenna-Emaintain high isolation (−20 dB). But antenna-E performs better isolationcompared to antenna-D. The notch at WLAN band (5.15-5.85GHz) is achievedby etching rectangular C-shaped slot on the both the radiators. In antenna-Etwo radiators are placed horizontally where as in antenna-D two radiatorsplaced orthogonally. It has been observed that the dimension of final outcome(antenna-E) is reduced by 33% compared to antenna-D without compromisingthe overall performance of the antenna.
