The feedback power of the antenna is monitored through the signal change output by the coupling port, and the effect of monitoring the working state of the communication equipment in real time is achieved;
the isolator is also called a isolator, and is a device for transmitting electromagnetic waves in one direction. It is composed of three branch lines which are symmetrically distributed at an angle of 120 degrees with each other. Because ferrite gyromagnetic material is adopted. The material generates gyromagnetic characteristics (also called tensor permeability characteristics) under the action of an external constant magnetic field; it is this gyromagnetic characteristic that causes a rotation of the polarization of the electromagnetic wave propagating in the ferrite (faraday effect) which causes the isolator to transmit with only a small loss in a given direction and a large loss in the other direction (isolation). Because the non-reciprocal unidirectional passing characteristic is provided, the signal output end and the load play the roles of being independent and mutually isolated. The high-power load of the isolator can absorb the reflected power of the impedance of the output end in the states of change, even open circuit or short circuit, and the like, thereby avoiding the mutual interference between signals and playing the role of protecting the power amplifier. Therefore, the antenna has wide application, can be used in a radar/communication system, enables signals to be isolated from each other, and can share the same antenna for receiving and transmitting signals.
