Abstract
A radio communication device includes an antenna for a predetermined frequency band, a radio communication circuit connected to the antenna, and a ground pattern connected to the antenna, a peripheral length of the ground pattern being 0.7 to 1.4 times as great as one wavelength of the predetermined frequency band. With the structure, it is possible to obtain a broader band characteristic without deteriorating the radiation efficiency of the antenna.
