Abstract :
In this study, the design and simulation of a circularly-bended antenna array at X-band for satellite applications is presented. Antipodal Vivaldi Antenna (AVA) is selected as an array element due to its wideband and end-fire characteristics. The proposed antenna, operating in the 8-12 GHz frequency range, provides good VSWR and high gain without degradation of radiation pattern caused by conforming operation. The design is intended to be used to in both satellite and ground systems with beam scanning capability.
