A Compact Design of Ultra Wide Band Antenna with 5.5GHz to 5.9GHz Dual Band Characteristics

Abstract

An innovative and compact design of microstrip antenna is introduced and presented in this Paper. The proposed patch antenna in the present paper is embedded with the square split ring resonator, Which is placed inside the circular substrate. A co-axial probe feed is used to excite the patch antenna. The proposed patch antenna is designed, and simulated using an soft HFSS simulation software. Incorporation of square SRR inside the substrate can produce sub-wave length resonant frequency. Various antenna parameters observed in this paper are VSWR, Return loss, Resonant frequency and gain. The proposed antenna produces improved results in the frequency band from 5.5GHz to 5.9GHZ. The results obtained are return loss-15dB, VSWR 1.8 and antenna gain 6.47dBi.
