PROBLEM TO BE SOLVED: To provide a dipole antenna system capable of widening bandwidth and reducing a deviation of a radiation pattern on a horizontal plane in a high frequency band, and to provide a method for arranging the dipole antenna system.SOLUTION: A dipole antenna system 1 includes: a power feeding part 2; a first conductor 10 forming a shape including a first large conductor part 11 whose height I1 is high and a first small conductor part 12 whose height I2 is low by forming a notch part 10B on a corner part of the long base B1C1 side of a trapezoid and arranged so that a short base A1D1 is turned to the power feeding part 2 side; and a second conductor 20 forming a shape including a second large conductor part 21 whose height J1 is high and a second small conductor part 22 whose height J2 is low by forming a notch part 20B on a corner of the long base B2C2 side of a trapezoid and arranged so that a short base A2D2 is turned to the power feeding part 2 side on the opposite side to the first conductor 10 through the power feeding part 2: where the first small conductor part 12 and the second small conductor part 22 are respectively formed as the same trapezoidal shape. 【課題】広帯域化が可能であるとともに、高周波数帯域において水平面内放射パターンの偏差を小さくすることができるダイポールアンテナ装置及びダイポールアンテナ装置の配置方法を提供する。【解決手段】ダイポールアンテナ装置１は、給電部２と、台形の長底辺Ｂ１Ｃ１側の角部に切欠き部１０Ｂを形成することにより高さＩ１が高い第一大導体部１１及び高さＩ２が低い第一小導体部１２を有する形状をなし、短底辺Ａ１Ｄ１を給電部２側に向けて配置される第一導体１０と、台形の長底辺Ｂ２Ｃ２側の角部に切欠き部２０Ｂを形成することにより高さＪ１が高い第二大導体部２１及び高さＪ２が低い第二小導体部２２とを有する形状をなし、給電部２を挟んで第一導体１０とは反対側に短底辺Ａ２Ｄ２を給電部２側に向けて配置される第二導体２０と、を備え、第一小導体部１２と第二小導体部２２とが、同一の台形状をなしていることを特徴とする。【選択図】図１
