Wireless communication device with two internal antennas
First Claim
1. A portable wireless communication terminal device having a data communication function and, a telephone function, comprising:
- a casing;
display means having a display section exposed through an opening of said casing;
a circuit board installed in said casing and having said display means arranged on a first surface of the circuit board;
a first antenna electrically connected to said circuit board and disposed on a second surface of the circuit board opposite to the display section of said display means; and
a second antenna electrically connected to said circuit board and mounted on a periphery of said display section of said display means,wherein said second antenna has an inverted-F type antenna structure, said second antenna including;
a radiative conductor;
a ground facing said radiative conductor;
short-circuiting means for connecting said radiative conductor to said ground; and
feeding means for feeding electric power to said radiative conductor.

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.
