Abstract
An antenna is realized by a simple mechanism without use of a dedicated antenna element. An antenna includes a first conductor 2b (2d) that has a first line length from a start point 4 to a folded point 3; and a second conductor 2b (2d) that has a second line length in a direction from the folded point 3 to the start point 4 and is electrically connected to the first conductor at the folded point 3. A first received signal with a first frequency is received with a first antenna length including both the first line length and the second line length. A second received signal with a second frequency is received with a second antenna length including only one of the first line length and the second line length.
Claims8
An antenna comprising:
- a first conductor that has a first line length from a start point to a folded point;
- and
- a second conductor that has a second line length in a direction from the folded point to the start point and is electrically connected to the first conductor at the folded point,
- wherein a first received signal with a first frequency is received by a conductor with a first antenna length corresponding to a length obtained by combining the first line length and the second line length,
- a second received signal with a second frequency is received by a conductor with a second antenna length corresponding to one of the first line length and the second line length, and
- one of the first and second conductors is a core line of a coaxial wire and the other thereof is an external conductor of the coaxial wire.
