Abstract

A MIMO antenna array has been presented in this paper, which has four rectangular microstrip patches as an antenna element(s). An elliptical slot is etched on every radiating patch. The antenna array is simulated in HFSS yielding resonating frequencies of 2.42, 3.49 and 4.98 GHz at S₁₁ <; -10 dB making it applicable for WLANs. RT Duroid 5880 has been used as substrate. The gain ranges from 7 to 11 dB at all resonant frequencies with narrow bandwidth, improving interference rejection characteristics of the proposed antenna. Complete design procedure, comprehensive analysis of mutual coupling among the patches and radiation patterns are also discussed.
