Zusammenfassung: | The invention provides an antenna reception device which can more suitably determine the receiving sensitivity at the receiving frequency of a product, and an electronic timepiece. The antenna reception device includes an antenna receiving radio waves, a board (21) including three or more connection pads (P1-P9), and connectors that respectively connect two of the connection pads to the antenna. The board (21) has at least one of two or more first electrodes connectable to a ground plane (G) and second electrodes connectable to a power supply point, has wirings having different first wiring distances from the first electrodes to the ground plane when the board (21) has the two or more first electrodes, and has wirings having different second wiring distances of signal lines extending from the second electrodes when the board (21) has the two or more second electrodes.
本发明提供能更合适地确定产品的接收频率下的接收灵敏度的天线接收装置以及电子钟表。天线接收装置具有:接收电波的天线;具有3个以上连接垫(P1~P9)的基板(21);将连接垫(P1~P9)当中任意2个与天线之间分别相连的连接部。基板21具有2个以上的能与接地面G连接的第1电极以及能与供电点 |
