Patent ID: 8185061

Claim:
A wireless terminal, comprising: an antenna which comprises: a first antenna element comprising a feeding point, a folding point, and a short point; a second antenna element that is branched from a first point between the feeding point and the folding point of the first antenna element; a stab short-circuiting a second point between the feeding point and the folding point of the first antenna element and a third point between the folding point and the short point of the first antenna element; and at least one frequency switching circuit to control an operating frequency of the first antenna element in accordance with a frequency control signal, the at least one frequency switching circuit being inserted between the folding point and the short point of the first antenna element; a plurality of RF circuits to perform an RF signal processing; an antenna switch to connect the antenna to one of the plurality of RF circuits in accordance with a connection control signal; and a generation unit configured to generate the frequency control signal and the connection control signal in accordance with switching between a plurality of wireless communication systems or switching between transmission and reception, wherein an electric length to the short point of the first antenna element from the feeding point of the first antenna element through the second point, the stab, and the third point is substantially ½ of a wavelength corresponding to a resonance frequency of the second antenna element.
