| Abstract: | A circularly polarized (CP) crossed dipole antenna backed with Perfect Electric Conductor (PEC) and cylindrical cavity reflectors are presented in this paper. The performance of these reflectors is compared here. A comparative study of CP antenna features on PEC and Cavitybacked reflectors to that of reference antenna is carried out in this work. The crossed dipole backed by a cylindrical cavity is able to achieve unidirectional radiation pattern, high gain, high front-to-back ratio along with an efficiency > 90%. The 0.26 λ0 × 0.23 λ0 (where λ0 is free space wavelength at 1.58 GHz) sized antenna backed by a cavity structure yields a total gain of 10.59 dBic at 1.58 GHz and a front-to-back ratio > 25 dB. This antenna can be applicable in Global Positioning Systems (GPS) and satellite communication systems. |
