ABSTRACT:
A substantially card shaped data communication receiver (100) for receiving radio frequency (RF) signals comprises receiver circuitry for recovering information included in the RF signals, an insulative frame (210), a first conductive panel (215) disposed over a first side of the frame (210), and a second conductive panel (220) disposed over a second side of the frame (210) such that the receiver circuitry is enclosed within the space defined by the frame (210) and the first and second panels (215, 220). The first and second panels (215, 220) have coupling members formed thereon for electrically coupling the first panel (215) to the second panel (220). The data communication receiver (100) further comprises a first conductor (510) for electrically coupling the first panel (215) and the receiver circuitry and a second conductor (505) for electrically coupling the second panel (220) to the receiver circuitry such that the first and second panels (215, 220) function as an RF antenna when disposed over the first and second sides, respectively, of the frame (210).
