ABSTRACT:
A small-sized mobile radio has a built-in antenna is high enough to enhance the antenna characteristics. In the mobile radio, a base plate is structured by a section (antenna-housing section) including a supply portion and a short-circuiting portion, for example, of an antenna element which affect the antenna characteristics, and a section (circuit-housing section) which is the rest of the base plate. The antenna-housing section is so positioned so as to keep the built-in antenna high enough, that is, to keep the space between the base plate and the antenna element large enough. On the other hand, the circuit-housing section is positioned toward the back of the cabinet to provide room for a display and a key section.
