PROBLEM TO BE SOLVED: To provide an antenna with a reduced size capable of reducing manufacturing costs by simplifying manufacturing steps.SOLUTION: An antenna according to the present invention includes a power feeding member, a first antenna, and a second antenna. The power feeding member includes a first power feeding part and a second power feeding part electrically isolated from each other. The first antenna slidably penetrates through the power feeding member, and a first contact part formed at its end is electrically coupled with the first power feeding part when being drawn. The second antenna includes a cylindrical pipe, a second antenna pattern, a second contact part, and a transmission line. The first antenna slidably penetrates through inside of the cylindrical pipe. The second antenna pattern is formed at one end of an outer face of the cylindrical pipe. The second contact part is formed at the other end of the cylindrical pipe and electrically coupled with the second power feeding part. The transmission line is electrically coupled with the second antenna pattern and the second contact part, and transmits signals received from the second antenna pattern to the second contact part. |
