Summary:PROBLEM TO BE SOLVED: To provide a light transmitting antenna, a window attached type communication module, and a peripheral monitoring unit capable of improving gain while suppressing degradation of transmittance.SOLUTION: In an antenna module 100 that operates as a patch antenna, a patch pattern 2 is formed by using a transparent conductive film having a predetermined transmittance and a predetermined conductivity on one side of a transparent base material 1 realized by using a transparent insulating material. In the patch pattern 2, a plurality of strong conductive patterns 22 formed linearly by using a conductive member having higher conductivity than that of the transparent conductive film is disposed. The width of the plurality of strong conductive patterns 22 is set to be equal to or less than a value assumed as the resolution of human eyes. The plurality of strong conductive patterns 22 are arranged in a central region of the patch pattern 2 at predetermined intervals Lp so as to follow the current flow induced at the time of resonance.SELECTED DRAWING: Figure 1 【課題】透過率の劣化を抑制しつつ、利得を向上させることができる光透過型アンテナ、窓部貼付型通信モジュール、及び、周辺監視ユニットを提供する。【解決手段】アンテナモジュール１００は、パッチアンテナとして動作するものであって、透明な絶縁材料を用いて実現されている透明基材１の片面には、所定の透過率及び所定の導電率を提供する膜である透明導電膜を用いてパッチパターン２が形成されている。また、パッチパターン２には、透明導電膜よりも導電性が高い導電部材を用いて直線状に形成されている複数の強導電パターン２２が配置されている。複数の強導電パターン２２の幅は、人間の目の分解能として想定される値以下に設定されている。複数の強導電パターン２２は、パッチパターン２の中央領域に、共振時に誘起する電流の流れに沿うように、所定の間隔Ｌｐをおいて配置されている。【選択図】図１
