Problems solved by technology
[0003] However, when the frequency-combining antenna requires independent electrical regulation, each output port of the phase shifter needs to introduce a combiner, which makes the antenna feeding network more complicated, lowers the manufacturability, and increases the cost
In order to solve this problem, several patents have introduced different integration technologies of combiners and phase shifters, but all of them have disadvantages such as complex structure, consistency of phase shifters, and hidden dangers in manufacturability.

The invention provides a microwave device and an antenna. The microwave device comprises a cavity, and a multilayer dielectric structure for dividing the cavity into an upper-layer cavity and a lower-layer cavity is arranged in the cavity. The multilayer dielectric structure comprises at least two dielectric substrates and a middle ground layer electrically connected with the cavity. Microwave networks are arranged in the upper-layer cavity and the lower-layer cavity, and metal grounds of the microwave networks of the upper-layer cavity and the lower-layer cavity are connected with the middleground layer, so that the cavity, the multilayer dielectric structure and the microwave networks in the upper-layer cavity and the lower-layer cavity form an upper independent strip line structure anda lower independent strip line structure to transmit signals. The strip line structures are formed by the cavity, the multilayer dielectric structure and the microwave networks located between the side walls of the cavity and the multilayer dielectric structure, so that signal transmission is achieved. The structure is simple, the complexity of an antenna feed network is reduced, the phase shiftconsistency is good, and the index stability of the antenna is improved.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a microwave device and an antenna. Background technique [0002] At this stage, with the continuous introduction of new standards and new spectrums, mobile operators are forced to seek antenna equipment that can support more spectrums. Using combining / duplexing technology, that is, introducing a frequency division combiner (also known as a duplexer) in a broadband antenna array can divide the broadband antenna into two narrowbands, thereby introducing more ports. [0003] However, when the frequency-combining antenna requires independent electrical regulation, each output port of the phase shifter needs to introduce a combiner, which makes the antenna feeding network more complicated, lowers the manufacturability, and increases the cost. In order to solve this problem, several patents have introduced different combiner and phase shifter integration technologies, but all have ...
