Abstract
A portable electronic device is provided that reduces resonant frequency fluctuation of an antenna caused changes in the state of bodys thereof, thereby enabling the communication signal quality to be stabilized. A cellular telephone devicehas an antennainstalled in an operation unit side bodythereof, and an electronic componentand an adjusting circuit, which is electrically connected to the electronic componentand adjusts the resonant frequency of the antenna, are installed in a display unit side body. A hinge portionconnects the operation unit side bodyand the display unit side bodyso as to freely change between a first state (closed state) in which the antennaand electronic componentare capacitively coupled, and a second state (opened state) in which the antennaand electronic componentare not capacitively coupled or capacitively coupled to a low degree.
