A Center Fed Multi-Band Antenna for Simultaneous Satellite Communication at C and Ku Bands
As the Navy requires increased data throughput via satellite communications at sea, the need for a vessel based SATCOM multi-band antenna operating at both C and Ku-bands is on the rise. The design of a compact, high performance, simultaneous C and Ku-band antenna and feed presents many technical challenges. Such challenges include mechanical packaging of the feed components with short focal length optics, broadband axial ratio that is less than 0.75 dB, and broadband high efficiency. This paper describes the design and testing of a multi-band coaxial antenna subsystem as part of the Navy Commercial Broadband Satellite Program (CBSP).
