This paper describes basic of circular polarization, fundamental concepts, theory and review study of the circularly polarized dielectric resonator antenna (CP DRA) over the last three decades. The latest techniques for generating the circular polarization as well as enhancing the performance are also covered.. CP DRA catches the potential application in the Satellite communication, mobile communication, GPS, WLAN, WIMAX, Mobile communication and Radar system. This paper also presents a design of polarization reconfigurable, left hand and right hand switchable cylindrical DRA ,by using two crossed slots of unequal length to couple energy from an aperture coupled microstrip line. Right hand circular polarization or left hand circular polarization can be achieved with a single feeding structure in the designed antenna. The designed antenna minimises fading caused by multipath effect. |
