Abstract

A microwave phase shifter comprises superposed conductor and dielectric plates, and a conductor strip carried by the dielectric plate. It comprises means, such as a piezoelectric biplate, for moving one of the plates in relation to the other thereby modifying the thickness of an air gap between the plates and consequently, modifying the phase constant of the phase shifter. The phase shifter can comprise at least one microstrip type impedance transformer in order to match to a microwave transmission line. When radiating elements are linked along the conductor strip, the phase shifter forms a lobe scanning network antenna.
