Abstract
A feed network includes an adjustable electromechanical phase shifter that comprises a main printed circuit board and a phase shifting unit. The adjustable electromechanical phase shifter is configured to shift the phase of an RF signal that is input to the feed network and provide the phase shifted RF signal to at least one radiating element that is positioned on a first side of a reflector of an antenna, where the phase shifting unit is formed on the surface of a first side of the main printed circuit board, and the first side of the main printed circuit board is a side that is closer to the at least one radiating element, and the main printed circuit board is positioned on the first side of the reflector.
