Abstract:
1. A panel antenna comprising: an array of radiating elements; a feed network connecting an input to said array of radiating elements; and a phase shifter assembly located in said feed network and configured to adjust the phasing of signals fed to said array of radiating elements, said phase shifter assembly comprising a moveable conductive component coupled to the input and capacitively coupled to a transmission line segment of the network between radiating elements, the conductive component or transmission line segment having a dielectric coating providing dielectric separation of the transmission line segment and the wiper conductive component; wherein the transmission line segment is a trace on a printed circuit board, the printed circuit board having an arcuate edge guide surface with an arc center proximate the coupling between the conductive component and the input; and further comprising a clip coupled to the printed circuit board to bias the conductive component against the printed circuit board about the arcuate edge guide surface.
