Abstract: A Beam-forming Network (BFN) includes a plurality of directional couplers (C,, C 2 , C 3 ) and phase shifters (P) which can interconnect both a transmitter and a receiver to the same group of radiating elements (1, 2, 3, 4) of an antenna even though the transmitter frequency band is different and well spaced from the receiver frequency band. This is accomplished, in accordance with the invention, by using directional couplers (C,, C 2 , C3) each of which has a variable response over a wide band of frequencies but which is designed so that its response over the transmitter frequency band is stable and its response over the receiver frequency band is also stable.

Abstract translation: 波束形成网络（BFN）包括多个定向耦合器（C1，C2，C3）和移相器（P），它们可将发射机和接收机互连到同一组辐射元件（1,2,3， 即使发射机频带不同并且与接收机频带很好地间隔，天线也可以是4）。 根据本发明，通过使用各自在宽频带上具有可变响应但是被设计成使得其在发射机频带上的响应是稳定的定向耦合器（C1，C2，C3）来实现的，并且 其对接收机频段的响应也是稳定的。
