INSTALLATION STRUCTURE OF ANTENNA

摘要

PURPOSE: To be housed in the main body of PC at the time of not using an antenna and to sufficiently show a function as an antenna. CONSTITUTION: At the time of not communicating, an analog circuit board 56 is housed in a housing 30 fixed to a housing part 24. At this time a cover 74 closes down a housing port 40 to prevent dust from entering the main body. At the time of drawing a drawer from the housing port 40 in the case of communication, an analog circuit board 56 with a pole antenna can be drawn together. As the pole antenna is positioned just over the bottom plate of the drawer as a ground plane and the cover of the circuit board 56, the antenna sufficiently shows the function as an antennae. In addition by drawing the circuit board 56 from the main board 12, heat can be wasted.
