Summary:To simplify a circuit configuration corresponding to a plurality of frequency bands.SOLUTION: An antenna device 1 includes an antenna unit A1 that receives radio waves corresponding to a plurality of first frequency bands (GPS L1 band, L2 band, GPS L5 band or QZSS L6 band) and outputs a reception signal, and a BPF35A that passes the reception signals in the two second frequency bands (GPS L1 band and L2 band) of three first frequency bands from among the received reception signals.SELECTED DRAWING: Figure 5 【課題】複数の周波数帯に対応する回路構成を簡単にすることである。【解決手段】アンテナ装置１は、複数の第１の周波数帯（ＧＰＳのＬ１帯、Ｌ２帯と、ＧＰＳのＬ５帯又はＱＺＳＳのＬ６帯）に対応する電波を受信して受信信号を出力するアンテナ部Ａ１と、受信された受信信号のうち、３つの第１の周波数帯のうちの２つの第２の周波数帯（ＧＰＳのＬ１帯及びＬ２帯）の受信信号を通過するＢＰＦ３５Ａと、を備える。【選択図】図５
