Abstract
A tunable phase shifter is provided which includes a dielectric substrate, a transmission line formed based on the dielectric substrate for carrying input and output signals and a dielectric disturber placed on top of the transmission line. The phase shifter further includes a phase shifting mechanism for adjusting at least one of a distance between the transmission line and the substrate and a distance between the transmission line and the dielectric disturber to effect phase shift.
