Portable wireless communication apparatus

A portable wireless communication apparatus comprising:

• a body comprising a circuit board disposed therein, a first recess defined therein, a first conductive resilient element disposed in the first recess and connected to the circuit board and a touch panel provided on the body;
• and
• a pen/antenna device comprising a pen for use on the touch panel to control the portable wireless communication apparatus and a telescopic antenna connected to the pen;
• the telescopic antenna being connected to the circuit board through the first conductive resilient element when the telescopic antenna is disposed in the first recess and including a first conductive tube connected to the pen, a joint telescopically inserted in the first conductive tube and a second conductive tube connected to the joint;
• and the joint enabling the first and second conductive tubes to be rotated relative to each other about two axes;
• wherein the first recess of the body is shaped in compliance with the pen/antenna device so as to entirely receive the pen/antenna when the telescopic antenna of the pen/antenna is reduced to a shortest length and inserted into the first recess.
