Abstract
Circuit modules having one, two or three double-sided printed circuit boards (PCBs). Each PCB can have coils formed as spiral traces on both sides thereof. The coils can all be connected together, in series or in parallel, to function as a coil antenna. Alternatively, selected ones of the spiral traces can be connected to function as one winding of a transformer, the other coils functioning as another winding of the transformer and connected to an external antenna. Electronic components can be mounted to a lower one of the PCBs, and in embodiments having two or three PCBs, the PCB overlying the lower PCB has a central opening to accommodate the electronic components. A ferrite rod antenna may be disposed in the opening, aligned parallel to the PCBs, to provide a dual-directional antenna system.
