Low Profile antenna for Multi-Band (X, Ku, and Ka SATCOM) including potential option for Ku band Tactical Common Data Link (TCDL)

There is currently a need for high data rate, dual frequency band airborne SATCOM communication with a very low profile antenna system to reduce drag, and footprint on the host aircraft fuselage. The need to switch frequency band without physical reconfiguration is essential given the evolving needs and geographic deployment regions in which our armed services have to operate. This proposal outlines the proposed Pacific Antenna Systems (PAS) effort to develop a very low profile, high bandwidth antenna system compatible with the requirements of the WGS satellite constellation and in accordance with the technical guidelines of MIL-STD-188-164B. The effort details the development of a high gain, highly efficient, X/Ka Band antenna which can be switched on-the-fly with no hardware reconfiguration. The antenna described shall be suitable for use in rotary wing or fixed wing aircraft. Additionally, the optional use of Ku Band SATCOM and the Dual Mode objective of a X\Ku\Ka SATCOM and Line of Sight TCDL shall be investigated during this proposed effort
