On a bottom surface of the non-ground area of the substrate, capacitance-forming electrodes are formed at positions opposed to the power supply terminal connection electrode and the ground terminal connection electrode, respectively. By capacitances caused by the capacitance-forming electrodes, being loaded to radiation electrodes, respectively, a resonant frequency in a fundamental mode can be set independently of a resonant frequency in a harmonic mode. | 04-28-2011 |
