To provide an antenna device capable of adjusting a timing for returning telemetry data of a signal processing module mounted on each of cascade-connected antenna panels.SOLUTION: An antenna device comprises: an active phased array antenna (APAA) 2 in which a plurality of antenna panels 3-1 to 3-N each having a signal processing module 4-1 to 4-N are cascade-connected; and a controller 1 that transmits a control signal to at least one antenna panel 3-1 and receives telemetry data from the antenna panel 3-1. The signal processing modules 4-1 to 4-N adjust a timing for returning telemetry data on the basis of a reception timing of the control signal.SELECTED DRAWING: Figure 1 【課題】縦続接続される各アンテナパネルに搭載される信号処理モジュールのテレメトリデータの返送タイミングを調整可能なアンテナ装置を得ること。【解決手段】信号処理モジュール４−１〜４−Ｎを有するアンテナパネル３−１〜３−Ｎが複数縦続接続されたＡＰＡＡ２と、少なくとも１つのアンテナパネル３−１に制御信号を送信し、当該アンテナパネル３−１からテレメトリデータを受信する制御部１と、を備え、信号処理モジュール４−１〜４−Ｎは、制御信号の受信タイミングに基づいて、テレメトリデータの返送タイミングを調整する。【選択図】図１
