Antenna for use with a radio installed in an expansion slot of a computer system
First Claim
1. A radio receiver/transmitter communication system for a computer terminal including an expansion slot for receiving expansion circuit boards and an internal compartment defining an enclosure in the housing of said computer terminal, said internal compartment separated from said expansion slot by a portion of said terminal housing, comprising:
- a stand-alone printed circuit board positioned within said enclosure of said internal compartment of said computer terminal;
a radio frequency communication medium etched on a first side of said stand-alone printed circuit board and operable within said enclosure of said computer terminal to support wireless communications;
a radio transmitter/receiver on a circuit board installed in said expansion slot; and
a data transmission cable connected to and providing a data communication pathway between said radio frequency communication medium and said radio transmitter/receiver.

Abstract
An antenna that may be retrofitted for incorporation in an internal compartment of a computer terminal when a radio transmitter or receiver is installed in an expansion slot of the computer terminal. The present invention provides a radio receiver/transmitter communication system for a computer terminal. The computer terminal includes an expansion slot operative to receive a radio transmitter or receiver and includes an enclosed compartment defined in the housing of the computer terminal. The enclosed compartment is separate from the expansion slot. The radio receiver/transmitter communication system includes a printed circuit board and a radio frequency communication medium. The radio frequency communication medium is etched on a first side of the printed circuit board, thereby forming a circuit board antenna, and the printed circuit board antenna is positioned within the enclosed compartment of the computer terminal. The radio communication system also includes a radio transmitter/receiver expansion board installed in the expansion slot and a connection cable connected to and providing a transmission path between the radio frequency communication medium of the circuit board antenna and the radio transmitter/receiver. The radio communication system is preferably implemented in a portable computer terminal that includes a the stylus pen slot as an internal compartment.
