Abstract
ABSTRACTIn this study, the relationship between ground slot length and operating guided wavelength of a rectangular microstrip patch antenna for different dielectric substrates is investigated. The microstrip antenna structure taken into consideration is consist of one open ended slot embedded inside the patch and one rectangular slot placed inside the ground plane. For each of the dielectric substrates (εr = 2.2, 2.4, 3.2, 3.55, 4.2, 4.4, 4.8, 6, and 8) simulation results in terms of resonance frequency, bandwidth, gain, and size reduction are found for different values of ground slot length. From the each stage of the antenna (for each dielectric substrate) the relationship between ground slot length and guided wavelength is formed by the help of simulated results and finally all these relations are combined into the proposed relationship. Four prototypes are fabricated (two prototypes using PTFE substrate and two using FR4 substrate) and tested. Good agreements are found between simulated and measured results. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2859–2864, 2016
