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 anten…
