Abstract
A portable wireless communication terminal device has a data communications function and a telephone function and includes a casing, a display having a display section exposed through an opening of the casing, a circuit board installed in the casing and having the display on one surface of the circuit board, a first antenna electrically connected to the circuit board and disposed on an opposite side to the display inside the casing, and a second antenna electrically connected to the circuit board and mounted on a periphery of the display inside the casing. The device maintains a stable antenna characteristic and communication quality even if it is placed on a table or if the fingers of a user cover the backside of the device.
