Abstract
A terrestrial transceiver is described, which is operable for exchanging RF signals with communication satellites. The transceiver has a patch antenna sensitive to signals within an L-Band RF range and operable for providing a gain to the RF signals. A metallic reflector of a characteristic dimension is operable for shaping a pattern of the RF gain of the patch antenna. A printed circuit board assembly (PCBA) has a dielectric substrate, an electronic component disposed upon the substrate, and a hole penetrating the substrate and disposed substantially within a central region thereof. Based on the dimension characteristic of the reflector and on a positioning and/or a dimension of the hole, the RF gain diverges over an angle from a boresight of the patch antenna.
