To provide an extension mast that is adopted to a use in an environment with a restriction such as lunar, can be housed compactly and developed, and is configured as an antenna integrated type.SOLUTION: An extension mast 200 at least comprises: a top board 2; a bottom board 1; a plurality of elastic vertical beams 3 connecting the top board 2 and the bottom board 1; add a wiring 70 which is connected to the top board 2 via a hole part 4 provided to the bottom board 1 to energize to each elastic vertical beam 3 between the top board 2 and bottom board 1 to contract it in a coli shape, and which releases the energization and stretches each elastic vertical beam 3 linearly. A first part 9d of the wiring 70 on the bottom board side is constituted by a cable 9 in order to be connected to an antenna element as an antenna integrated type.SELECTED DRAWING: Figure 4

    【課題】月面等に代表されるような、制約がある環境での利用に適した、コンパクトに収容し且つ展開できる、アンテナ一体型として構成された伸展マストを提供する。【解決手段】天板2と、底板1と、当該天板2と当該底板1とを接続する複数の弾性縦梁3と、当該底板1に設けられた孔部4を通じて当該天板2に接続されることで、当該天板2と当該底板1との間の前記弾性縦梁3へ付勢してコイル状に収縮させると共に、当該付勢を解除して前記弾性縦梁3を直線状に伸展させることができる引索70と、を少なくとも備える伸展マスト200において、前記引索70の前記底板側の第1部分9dが、アンテナ素子へ接続するためのケーブル9で構成されていることで、アンテナ一体型として構成される。【選択図】図4
