To detect biological information such as a heartbeat and respiration of a subject reliably and stably without imposing a burden on the subject.SOLUTION: A biological information monitoring device includes: an antenna device consisting of at least one antenna disposed close to a subject; a signal generation part for generating a high frequency signal; and a displacement detection part for detecting physical displacement of the subject using the high frequency signal. The antenna includes a dipole antenna, in the center of which an electric power supply part for supplying the high frequency signal is provided, a coaxial line for supplying the high frequency signal to the electric power supply part, and a conductor element of 1/4 wavelength, one end of which is short-circuited to an external conductor of the coaxial line.SELECTED DRAWING: Figure 16 【課題】被検体に負担をかけることなく、被検体の心拍や呼吸などの生体情報を、高い信頼性で安定に検出できるようにすることである。【解決手段】一実施形態の生体情報モニタ装置は、被検体に近接して配設される少なくとも１つのアンテナからなるアンテナ装置と、高周波信号を生成する信号生成部と、前記高周波信号を用いて、前記被検体の物理的変位を検出する変位検出部と、を備え、前記アンテナは、前記高周波信号が給電される給電部が中央に設けられたダイポールアンテナと、前記給電部に前記高周波信号を給電する同軸線路と、一方の端部が前記同軸線路の外導体に短絡される１／４波長の導体素子と、を有して構成される。【選択図】 図１６
