Abstract :
A compact X/Ka bands feeder antenna has been proposed for a Cassegrain type reflector antenna board on a planetary exploration satellite. A sequentially rotated array in X band and a helical array in Ka band are employed for realizing the circular polarization. In the X band array, the unique feeding method has been developed for reducing cross polarization level of the sequential array and in the Ka band array, the compact configuration has been realized by positioning it within the space of the X band elements.
