Abstract

The present disclosure relates to couplers suitable for use in communications systems. The coupler comprises: a main conductive line comprising a first main section and a second main section; a first auxiliary conductive line comprising a first auxiliary section and a first end portion, wherein the first auxiliary section is configured to couple with the main conductive line to generate a first coupled signal; a second auxiliary conductive line comprising a second auxiliary section and a second end portion, wherein the second auxiliary section is configured to couple with the main conductive line to generate a second coupled signal; a transmission module that is configured to combine the first coupled signal and the second coupled signal into an output signal of the microstrip coupler and to pass the output signal to an outlet; and a coupled port coupled to the outlet and used for outputting the output signal.

Dependent claims

A microstrip coupler, comprising:

a main conductive line comprising a first main section and a second main section;
a first auxiliary conductive line comprising a first auxiliary section and a first end portion, wherein the first auxiliary section is adjacent and spaced apart from the first main section and is configured to couple with the main conductive line to generate a first coupled signal;
a second auxiliary conductive line comprising a second auxiliary section and a second end portion, wherein the second auxiliary section is adjacent and spaced apart from the second main section and is configured to couple with the main conductive line to generate a second coupled signal;
a transmission module comprising a first inlet, a second inlet and an outlet, wherein the first inlet is coupled to the first end portion, the second inlet is coupled to the second end portion, and the transmission module is configured to combine the first coupled signal from the first end portion and the second coupled signal from the second end portion into an output signal of the microstrip coupler and to pass the output signal to the outlet;
and
a coupled port coupled to the outlet and used for outputting the output signal.
