摘要：
In an antenna apparatus proposed by the present invention, two inverted-F antennas having the same characteristics are supplied with power with phase difference of 180 degrees respectively. Therefore only radio wave of polarized wave in a predetermined direction can be radiated and deterioration in antenna characteristics due to leak currents can be prevented.
