Dual (X and Ka) band downlink operation is demanded scientific satellite missions, to facilitate much higher data rate and to increase the available radio channels. A combinations of a corrugated horn (for X band) and a disk-on-rod antenna (for Ka band) have used as a primary feed for a satellite-borne dual-band reflector antenna, but its volume was not satisfactorily small. The anothers proposed a combination of a sequential four-element array of rectangular microstrip antennas fed with L-shape probes for X band and a four-element array of helical antennas for Ka-band, to realize a small-volume, light-weight circular-polarized primary radiator. This paper reports the performances― VSWR, XPD , and radiation patterns of a prototype radiator. |
