摘要：
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.
