摘要： A phase shifter includes a substrate; a signal line formed on a specific region in an upper surface of the substrate; and an air gap which is formed within the substrate and changes effective permittivity of the substrate to delay phase of a signal supplied to the signal line. The phase shifter delays a phase of a signal by controlling effective permittivity using an air gap, thereby having outstandingly low insertion loss as compared to existing phase shifters. Further, the phase shifter can be manufactured in a same length as a reference line so that the phase shifter can be in a compact size.

摘要： A wireless communication module includes a plurality of monolithic millimeter-wave integrated circuits (MMICs) for signal processing attached to the top surface of a multi-layer low temperature co-fired ceramic substrate; a planar transmission line formed on the top surface of the multi-layer substrate for communications between the MMICs; a metal base attached to the bottom surface of the multi-layer substrate and having an opening to which an antenna is attached; a plurality of vias for connecting the metal base and the planar transmission line within the multi-layer substrate to establish a uniform potential on a ground plane of the multi-layer substrate; an embedded waveguide formed in the opening surrounded with the vias within the multi-layer substrate; and a planar transmission line-to-waveguide transition apparatus for the transition of waves between the planar transmission line and the embedded waveguide.
