Abstract: Approaches, techniques, and mechanisms are disclosed for allowing multiple distinct and diverse wireless services (e.g., Wi-Fi, Bluetooth, Radio Frequency for Consumer Electronics (RF4CE), ZigBee, etc.) to share common frequencies while utilizing a single set of antennas. Among other potential benefits, the techniques may permit the sharing of common frequencies amongst multiple services with reduced (or no) interference amongst the services relative to conventional designs, which, depending on the embodiment, may increase performance, improving manufacturability, save design and material cost, and so forth. According to one embodiment, a multi-input directional coupler printed circuit may be implemented for multiple wireless services. This device may include a single directional coupler with reduced or no loss, placed in series with two combiners that provide high isolation for wireless signals. The device may thus allow multiple wireless services with potentially different protocols to share the same or different frequency bands using a single antenna.
