Abstract:
Embodiments of the disclosure relate to a high-directivity directional coupler, and related methods and systems. The high-directivity directional coupler includes a first microstrip and a second microstrip disposed parallel to the first microstrip. The high-directivity directional coupler inherently generates an even mode current and an odd mode current in the second microstrip. The second microstrip provides a linear forward path for conveying the even mode current and a non-linear return path for conveying the odd mode current. The non-linear return path is longer than the linear forward path to compensate for phase velocity difference between the even mode current and the odd mode current. As a result, the odd mode current and the even mode current in the second microstrip can destructively cancel out each other, thus rendering high-directivity without compromising other performance aspects of the high-directivity directional coupler.

Claim (Index 1):
A wireless distribution system (WDS), comprising:\n a plurality of remote units configured to:\n receive and convert a plurality of downlink digital communications signals into a plurality of downlink radio frequency (RF) communications signals for distribution to client devices; and \n receive a plurality of uplink RF communications signals from the client devices and convert the plurality of uplink RF communications signals into a plurality of uplink digital communications signals; and \n a central unit configured to:\n distribute the plurality of downlink digital communications signals to the plurality of remote units; and \n receive the plurality of uplink digital communications signals from the plurality of remote units; \n wherein at least one selected remote unit among the plurality of remote units comprises a high-directivity directional coupler, comprising:\n a substrate; \n a ground plane; \n an input port configured to receive an input signal; \n an output port configured to output the received input signal as an output signal; \n a coupled port configured to output a coupled signal proportional to the input signal; \n an isolated port configured to provide isolation to the input signal and the coupled signal; \n a first microstrip, the first microstrip configured to convey the input signal from the input port to the output port; and \n a second microstrip configured to:\n provide a linear forward path for conveying an even mode current from the coupled port to the ground plane; and \n provide a non-linear return path longer than the linear forward path for conveying an odd mode current in an opposite direction from the even mode current, the at least one selected remote unit further comprising: \n \n a power amplifier coupled to the input port of the high-directivity directional coupler and configured to amplify a selected downlink RF communications signal among the plurality of downlink RF communications signals.
