Abstract: An antenna is constituted in which a variable capacitance capacitor portion Ct is connected between an antenna element and a ground. In the variable capacitance capacitor, a plurality of variable capacitance elements using a thin film dielectric layer whose dielectric constant is changed by a voltage applied are connected in parallel with regard to direct current component and in series with regard to high frequency component between an antenna-element-side terminal and a ground-side terminal. The capacitance change ratio of the variable capacitance capacitor that depends on the bias signal can be utilized to the maximum so as to perform impedance matching so that the electrical length of the antenna element is changed, and thus, the operating frequency can be changed. In addition, the antenna having small waveform distortion and intermodulation distortion, high power handling capability and low loss at high frequencies can be realized.
