Compact EBG ground plane microstrip antenna for broad bandwidth applications

Abstract

In this article, a novel microstrip antenna with EBG ground plane is proposed for broad bandwidth applications. A 27 mm × 27 mm patch is designed and a slot of 20 mm × 20 mm is made on it. Slots improve the bandwidth at the cost of introduction of side lobes in the radiation pattern. To absorb these side lobes and to enhance the gain, EBG mushroom structures were introduced. The whole structure when simulated provides a gain of 4.1 dBi and an impedance bandwidth of 721 MHz around 4.8 GHz and 1,200 MHz around 7.6 GHz. Measured results shows good agreement with the simulated results and thus validates this design. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:555–557, 2016

Enhancement of Gain and Bandwidth using EBG Structure for Textile Antenna

“…Dual band microstrip antenna is designed using mushroom type EBG structure and resonant at 4.8 GHz, 7.6GHz with gain of 4.1dBi. Multiple slots created on patch and FR4 material is used for the substrate [9]. The impedance matching network also augments the bandwidth and leads to reduction in the return loss but desirable configuration is not obtained [10].In [11], 15x7 cells are used as Metasurface for enhancement of bandwidth and gain of Dipole antenna, resonant from 4.15 GHz to 5.85 GHz .…”
