【発明の名称】デュアル移相器を有する空間給電アレイ・アンテナ
Document Type and Number:
Japanese Patent JP3118247
Kind Code:
B2
Abstract:
An array antenna (10) for a radar includes a phase shifter arrangement wherein, in the transmitting mode, ferrite phase shifters (35) are used to collimate and direct a beam of transmitted radio frequency energy originating at a feed horn and, in the receiving mode, amplifiers (45) and diode phase shifters (37) are used to amplify and to focus received radio frequency energy on a feed horn. Each front antenna (31) is coupled by a switch (39), limiter (43), amplifier (45), diode phase shifters (37), and a circulator (41) to the corresponding rear antenna (33), and the rear antenna (33) is coupled through the circulator (41), the ferrite phase shifters (35), and the switch (39) to the front antenna (31).
