Purely passive, mechanically steered waveguide-fed horn arrays are good candidates to satisfy the current need for low-to-medium-profile antennas for mobile user terminals for SATCOM applications. In this work, a unique waveguide feed architecture is proposed, which enables the realization of grating lobe-free, wideband, low-profile waveguide-fed horn arrays operating with dual circular polarization...
The details of two product concepts and the hardware realization aspects for low profile Ku-/Ka-band land mobile terminals for high data rate satellite communications are described. Beside the competitive low cost approach, the non-obstructive design and lower weight are key issues for many applications to achieve a broad customer acceptance. The introduction of a proprietary planar antenna technology...
