Omni-directional dual-band patch antenna for the LMDS and WiGig wireless applications

Abstract

In this paper an omnidirectional dual band monopole antenna at 28 GHz and 60 GHz which is fit for indoor and outdoor wireless applications is developed. The proposed antenna consists of two rectangular patches with a T folded patch. The design, analysis, and optimization processes through this article are executed by the numerical method, Finite Element Method (FEM) and verified with another numerical method, Finite integration Technique (FIT). Good agreement between the results by these two simulators is obtained. The proposed antenna has achieved dual bands with omnidirectional patterns. The first band at 28 GHz is extended from 27.5 GHz to 28.958 GHz with 5.1 % bandwidth and total efficiency of more than 93% along the entire band which serves the LMDS band. The second band at 60 GHz is extended from 45.2 GHz to 84.4 GHz which serves the WiGig band with bandwidth of 60.6% and total efficiency of 85.5% along the entire band. The proposed antenna performance makes it a good candidate for the fifth generation (5G) applications. � 2018 Advances in Science, Technology and Engineering Systems. All rights reserved.
