ABSTRACT:
A substantially two-dimensional integrated phase shifter and radiator module wherein a plurality of phase shifting elements are deposited in microstrip configuration on one side of a common substrate, and at least one radiating element is constructed from ground plane metallization on the other side of the substrate. Electrical coupling between the output of the phase shifter and the radiator is accomplished by means of a pin interconnect which extends vertically through the substrate. The phase shifting elements are serially connected and positioned in predetermined patterns on the substrate so as to maximize circuit density, without any adverse electrical interaction with the radiator. Additionally, the serially connected phase shifting elements are each connected to individually receive a separate DC control voltage in order that varying degrees of phase shift may be introduced into microwave signals which are coaxially fed into the input terminal of the phase shifting circuitry.
