| Zusammenfassung: | A planar antenna has a radiating element that radiates electric wave, and an earthing conductive plate that reflects the electric wave radiated from the radiating element. There is formed a space between the earthing conductive plate and the radiating element. The radiating element has a strip-shaped central conductive part with a length corresponding to the half wavelength of a first transmission radio frequency signal, and strip-shaped conductive parts with a length corresponding to the half wavelength of a second transmission radio frequency signal that has a frequency different from that of the first transmission radio frequency signal. |
