The utility model provides an antenna which is excellent in axial ratio and corresponds to a plurality of frequency bands. The antenna provided by the utility model comprises a dielectric body with a patch electrode; and a circuit board having a power feeding part. Four electrode-side feed terminals (p11-p14) are formed on the patch electrode. Four substrate-side power supply terminals that are conductively connected to the four electrode-side power supply terminals (p11-p14) are formed in the power supply circuit. Reception signals (power) are supplied to the electrode-side feed terminals (p11-p14), each of which has an equal amplitude and has been phase-shifted by 90 degrees. 本实用新型提供轴比优异且与多个频带对应的天线。本实用新型的天线具备：具有贴片电极的介电体；和具有馈电部的电路基板。在贴片电极形成有四个电极侧馈电端子(p11～p14)。在馈电回路形成有与四个电极侧馈电端子(p11～p14)导通连接的四个基板侧馈电端子。对电极侧馈电端子(p11～p14)供给有为等振幅且各个以90度进行相位偏移后的接收信号(电力)。
