A staircase hexagonal shaped microstrip patch antenna for multiband applications

Abstract

As seeing the more demand of multiband antennas for wireless communication, this Staircase-Hexagonal shaped antenna has designed. The merit of antenna eight resonance frequencies are 3.13 GHz, 8.89 GHz, 10.69 GHz, 16.79 GHz, 20.37 GHz, 26.06 GHz, 30.13 GHz, 36.26 GHz with widely used gain 5.17 dBi, 9.12 dBi, 15.83 dBi, 6.05 dBi, 5 dBi, 5.84 dBi, 5.34 dBi, 3.79 dBi respectively. These resonance frequencies are achieved less than -10dB return loss. These output simulated by Ansoft HFSS (High Frequency Structure simulator) software. This antenna is printed on Rogers substrate whose full size has been taken 30mm × 30mm and 1.6mm height. The relative permittivity and loss tangent of Roger substrate are 3.0 and 0.0013 respectively. In this paper, a novel U-Shaped and Hexagonal has been abolished on rectangular radiator patch, also staircase introduced on upper and lower edges. Simulated return loss (S11), gain, directivity, and VSWR are discussed.
