Reduced size phase shifter

Abstract

A reduced size phase shifter provides the orientation of the microwave beams. The phase shifter includes RF connector (4) that provides the entrance of the coaxial transmission line (8) into the phase shifter (1), dielectric plate (7) with high dielectric constant that provides the gradual transformation of the quasi TEM mode carried by means of the micro-strip transmission line (6) into TE10 mode carried on the twin-toroid structure (5).

Claims

1. A phase shifter providing steering of microwave beams, comprising: a RF connector providing a connection of a coaxial transmission line into the phase shifter; a micro-strip transmission line providing an interface between the RF connector and a dielectric plate, wherein, the dielectric plate with a high dielectric constant provides a gradual transformation of a quasi TEM mode carried by means of the micro-strip transmission line into a TE10 mode carried on a twin-toroid structure.

2. The phase shifter according to claim 1, wherein, the dielectric plate with the high dielectric constant has no metal pattern.

3. The phase shifter according to claim 1, wherein, the dielectric plate is located on the micro-strip transmission line.
