MICROWAVE PHASE SHIFTER AND USE THEREOF IN AN ARRAY ANTENNA

摘要

A microwave phase shifter including a microwave waveguide with an electro-optic element (1) between two elements (3, 4) made of materials having a higher permittivity than the electro-optic element. The electro-optic element may be controlled using means for applying a biasing electric field. A microstrip (2) is inserted into the electro-optic element. Controlling the orientation of the molecules of the electro-optic element enables varying of the index of the electro-optic element observed by the field of a microwave. Said microwave phase shifter is useful in a scanning antenna.
