    DESIGN OF A DUAL FEED CIRCULAR PATCH ANTENNA WITH 90° HYBRID COUPLER
    Keta Meswania*, Falguni Raval

    A convectional microstrip antenna having radiating patch on dielectric substrate supported by ground plane having an attractive features and planar structure which is inherently used in practical application. Paper represents design of circular patch antenna fed via 90° hybrid coupler in order to obtain circular polarization. A two port circular microstrip patch antenna was investigated in this paper. The antenna was designed for operating in S band (2 – 4 GHz, with centre frequency 2.12 GHz) frequency range with a circular polarization. The paper also presents the detail steps of designing the circular patch microstrip antenna and the simulated result, ANSOFT HFSS software was used to compute the S11, gain, current distribution and axial ratio of the antenna, which has application in monopulse radar and satellite communication.
