System Development of Transmitting Conformal SATCOM Array Antenna Structures(CSAAS)


== Abstract ==

This study presents the development results of Conformal SATCOM Array
Antenna Structure(CSAAS) for transmitting. Tile Type antenna with 8x8 antenna element
array has been developed instead of reflector antenna. 8x8 tile antennas are arrayed on the
curved surface with one directional curvature to simulate aircraft skin configuration. Housing
has the grid structure to minimize out-of-plane deformation that affects the antenna
performances. Tile antennas are attached to the surfaces between grids. Radome is designed
as an A-sandwich type to carry some distributed skin load and glass epoxy material with
lowest dielectric constant and loss tangent was used for the best electromagnetic performance.
One tile antenna is designed with a separate data control and power connection for vertical
and horizontal polarization. The static structural strength of the housing and impact strength
of the radome were verified by the analysis and tests. Beam pattern test, beam control test and
beam steering test are performed in an anechoic chamber for the transmitting CSAAS. The
results of structural and electromagnetic tests showed that the design objects met the goal
successfully.
