Phasenschiebertafel mit vier Phasenzuständen und ihre Anwendung bei einer Höchstfrequenzlinse und einer Antenne mit elektronischer Strahlschwenkung

摘要

A phase-shifter panel with four phase states, includes conducting wires (F) arranged parallel to the direction of the electric field of an incident wave on a dielectric support (1); each wire bears at least two diodes (D1, D2) mounted in opposition and supplied via control conductors (51, 52, 53) which enable the state of the diodes to be controlled independently of one another. The geometrical and electrical characteristics of the panel are such that to each of the states of the diodes corresponds a given value of phase shift. Conductors (74, 75) parallel to the control conductors are arranged towards the periphery of the support (1). A stack of such panels forms an active microwave lens for an electronic scanning antenna. <IMAGE>
