Abstract
The present invention provides an antenna for a radio device that has sufficient mounting strength with little deterioration in antenna property. A first antenna and a second antenna are provided substantially parallel to each other at both ends of a circuit board Feeding points are provided at one end of first antenna and second antenna , and are fed in equiphase. As radio-frequency currents are in equiphase, vertically polarization are radiated, but horizontal radio-frequency currents are in antiphase, so horizontally polarization are not radiated. Furthermore, antennas may be formed by the mounting portions of the circuit board on the housing.
