Title
(EN) A WAVEGUIDE ANTENNA FRONT END
(FR) CIRCUIT D'ENTRÉE D'ANTENNE À GUIDE D'ONDE
Abstract
(EN)
In embodiments of the present invention, an antenna front end (100,200) includes at least two diplexers (110, 120, 210, 220). Each of the diplexers is defined with a channel within a single material block. Each channel is shaped to provide a diplexer which includes a coupler (115, 215), a receive band filter (140A, 140B, 240A, 240B) and a transmit band filter (130A, 130B, 230A, 230B), which are adjoined and matched to form a continuous waveguide channel. Some embodiments further include a transmit hybrid coupler (150, 250) and/or a receive hybrid coupler (160, 260). The transmit hybrid coupler is formed as a channel within the material block and adjoined and matched to the two transmit band filters. The receive hybrid coupler is formed as a channel within the material block and adjoined and matched to the two receive band filters.

Dans les modes de réalisation de la présente invention, un circuit d'entrée d'antenne (100, 200) comprend au moins deux diplexeurs (110, 120, 210, 220). Chacun des diplexeurs est défini avec un canal à l'intérieur d'un bloc de matériau unique. Chaque canal est façonné pour former un diplexeur qui comprend un coupleur (115, 215), un filtre de bande de réception (140A, 140B, 240A, 240B) et un filtre de bande d'émission (130A, 130B, 230A, 230B), qui sont contigus et adaptés pour former un canal de guide d'onde continu. Certains modes de réalisation comprennent en outre un coupleur hybride d'émission (150, 250) et/ou un coupleur hybride de réception (160, 260). Le coupleur hybride d'émission est formé sous forme de canal dans le bloc de matériau et contigu et adapté aux deux filtres de bande d'émission. Le coupleur hybride de réception est formé sous forme de canal à l'intérieur du bloc de matériau et contigu et adapté aux deux filtres de bande de réception.
