ABSTRACT:
A broadband, inductively coupled, duplex, radio frequency (RF) transmission system for communcating between a central unit (10) and a plurality of remote units (31) is disclosed. The central unit (10) includes an RF signal source (11) and an RF receiver (21) connected to one end of a balanced transmission line (25) via a signal splitter (15) and a transmission line impedance matching network (27). Each remote unit (31) includes a receiving section (33) and a transmitting section (35) separate from one another. Each receiving section (33) and each transmitting section (35) includes U-shaped couplers (37,43) positioned so as to overlie the balanced transmission line (25). The U-shaped couplers (37,43) are oriented such that the cross-members of the U-shaped couplers (37,43) lie orthogonal to the balanced transmission line (25) and the legs of the U-shaped couplers (37,43) lie parallel to the balanced transmission line (25). The legs of the U-shaped couplers (37,43) are connected to electronic transmit and receive system RF receivers and Rf signal sources (41,47), via impedance matching networks (39,45).
