PROBLEM TO BE SOLVED: To provide an antenna device including monopole type respective large sized antenna elements that are self-erected without requiring many branch lines.SOLUTION: The antenna device includes: an excitation part having at least three excitation conductor posts, each one end of which is fixed to a base structure by sandwiching an insulator, and erected by supporting each other, and to which a high frequency signal of a predetermined frequency is supplied from each of the one end sides; and a grounded surface conductor provided in the surrounding of the excitation part.SELECTED DRAWING: Figure 1 【課題】 多数の支線を必要とせずに自立させた、モノポール型のそれぞれの大型のアンテナ素子を備えたアンテナ装置を得る。【解決手段】 それぞれの一方の端が基礎構造物に絶縁物を挟んで固定され、互いに支えあいながら直立し、それぞれの前記一方の端の側から、決められた周波数の高周波信号が給電される、少なくとも３本の励振用導体柱を有する励振部と、前記励振部の周囲に設けられた、接地された地表導体とを備えるようにする。【選択図】 図１
