Abstract
ABSTRACTThe dual frequency rectangular microstrip antenna (RMSA) using slot has been brought in this article. By embedding narrow open rectangular ring slot close to the boundary of rectangular patch of single layer and single feed, dual frequency operation can be easily obtained. The slot provides reactive loading around the resonance frequency of rectangular patch at a consequence dual frequency operation has been obtained. The proposed design exhibits two contiguous resonant modes with similar polarization and radiation characteristics. This performance of the antenna makes size reduction compared with simple RMSA without slot. These two resonant modes are excited at frequencies near the fundamental resonant mode of RMSA without slot. By controlling the width and gap spacing of narrow open rectangular ring slot antenna, the frequency ratio is tuned in the range 1.28–1.42. The input impedance, return loss, and radiation characteristics of the antenna are analyzed using HFSS. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:2448–2452, 2015
