| description | To obtain an array antenna device capable of suppressing a spurious component caused by a harmonic wave independently of a device configuration to which the array antenna device is to be applied.SOLUTION: An array antenna device comprises a plurality of antenna elements, a plurality of transmission/reception modules, and a synthesis distribution circuit. Each transmission/reception module comprises a harmonic suppression circuit 3 that suppresses a harmonic signal included in a reception signal. Each harmonic suppression circuit 3 comprises: a transmission line 8 connecting between the antenna elements and the synthesis distribution circuit; and short stubs 31-1 and 31-2 each branched from a different branch point in a midway on the transmission line 8. A distance between the short stub 31-1 and the short stub 31-2 is set to a random, different length among the plurality of harmonic suppression circuits 3.SELECTED DRAWING: Figure 2
【課題】適用する装置構成に依らずに、高調波によるスプリアス成分を抑圧可能なアレイアンテナ装置を得ること。【解決手段】アレイアンテナ装置は、複数のアンテナ素子と、複数の送受信モジュールと、合成分配回路と備える。各々の送受信モジュールは、受信信号に含まれる高調波信号を抑圧する高調波抑圧回路３を備える。各々の高調波抑圧回路３は、アンテナ素子と合成分配回路とを結ぶ伝送線路８と、各々が伝送線路８の途中の異なる分岐点から分岐するショートスタブ３１－１，３１－２を備える。ショートスタブ３１－１とショートスタブ３１－２との間の距離は、複数の高調波抑圧回路３の間でランダムな異なる長さに設定されている。【選択図】図２ |
