Abstract:
PURPOSE: To make the radio equipment having a built-in antenna small.
CONSTITUTION: A so-called inverse-F type antenna is adopted for the antenna, in which a narrower gap than the wavelength is provided and which has a ground plate 4b and a radiation element 4a connected to each other at least by one position. Circuit components of the radio equipment are arranged between the two conductor plates 4a, 4b of the antenna and large sized metallic components in the circuit components are arranged at a position apart from the connection position between two conductor plates. The radio equipment is made small by integrating the circuit components and the antenna.
