ABSTRACT:
An antenna structure is composed of an antenna seat, a terminal, and an antenna set. The antenna set includes antennae, a matching circuit, conducting wires, and a lead wire. By the conducting wires and matching circuit connected on the antennae, an impedance matching can be achieved to be coupled with frequency of radio wave signal to be received for reducing a standing-wave ration, when the antenna are receiving the radio wave signal. In addition, the frequency and wavelength of radio wave signal received by the antennae can be adjusted by changing lengths of conducting wires.
