    Design of low-cost, circularly polarized, and wideband U-slot microstrip patch antenna with parasitic elements for WiGig and WPAN applications
    (Applied Computational Electromagnetics Society (ACES), 2019) Ibrahim M.S.; Department of Communications and Networks Engineering; College of Engineering; Prince Sultan University; Riyadh; 11586; Saudi Arabia; Department of Electrical Communication and Electronic Systems Engineering; College of Engineering; Modern Sciences and Arts University; 6th October; 12566; Egypt
    In this article, a well matched U-Slot Microstrip Patch Antenna (MPA) with two paratactic elements is designed and simulated. The antenna is designed to resonate at 60 GHz (V-band) and exhibits a wideband extend from 53.3 GHz to 60.8 GHz with more than 87% total efficiency. The presence of U-slot makes a current perturbation in the antenna which contributes to generate a Circular Polarization (CP). The 3-dB Axial Ratio (AR) is extended from 56 � 57.2 GHz (~ 1.2 GHz bandwidth). The analysis and optimization processes throughout this paper are carried out using Finite Element Method (FEM) and verified with Finite Integration Technique (FIT). Good agreement between the results by the two simulators is obtained. Hence, the performance of the proposed antenna makes it a good candidate for fifth generation applications at V-band like Wireless Gigabit Alliance (WiGig) and Wireless Personal Area Network (WPAN). � ACES

    Omni-directional dual-band patch antenna for the LMDS and WiGig wireless applications
    (ASTES Publishers, 2018) Ibrahim M.S.; Department of Communications and Networks Engineering; College of Engineering; Prince Sultan University; Riyadh; 11586; Saudi Arabia; College of Engineering; Modern Sciences and Arts University; 6th October City; Egypt
    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.
