Abstract
Provided is an antenna reception device including an antenna, a board including three or more electrodes, and two connectors that respectively connect two of the electrodes to the antenna. The electrodes include a first electrode that is connected to a ground and second electrode that is connected to a feed point. The board includes a first signal line between the ground and the first electrode and a second signal line between the feed point and the second electrode. The electrodes include two or more first electrodes and/or two or more second electrodes, and the board includes two or more respective first signal lines with different lengths and/or two or more respective second signal lines with different lengths.
Claims6
An antenna reception device comprising:
- an antenna that receives a radio wave;
- a first electrode that is connected to a first signal line connecting the first electrode to a ground and that is connected to a second signal line connecting the first electrode to a feed point, the first electrode including two or more first electrodes;
- a board including a plurality of electrodes including the two or more first electrodes;
- and
- a connector that can connect the first electrode and the antenna,
- wherein at least one of the first signal line and the second signal line that are connected to the first electrode is a relay line connecting the two or more first electrodes,
- wherein when the connector is connected to one of the two or more first electrodes, a path to the ground or a path to the predetermined circuit is settable by connecting the two or more first electrodes and the relay line in between from the antenna.
