Slot and corner truncation for enhancing bandwidth of circularly polarized patch antenna
This paper presents the bandwidth enhancement of patch antenna using diagonal slot and corner truncations. The antenna is intended to have circular polarization and operate at L-band frequency. Initially, a conventional patch antenna resonates at the L-band frequency of 1.27GHz is designed. Then, by adding a diagonal slot and corner truncations, the antenna parameter, i.e. −10dB working bandwidth, is analyzed. The antenna which is deployed on an FR4 epoxy dielectric substrate is fed using proximity coupling technique through a microstrip line beneath the patch. From the result, it shows that the impedance bandwidth of antenna is widened up to 60MHz or 200% with the axial ratio bandwidth of 200MHz in the frequency range from 1.16GHz to 1.36GHz.
