Wilkinson power splitters are widely used passive devices in wireless communication systems that are responsible for distributing input signals to multiple output ports. Due to their simple, compact, and high-performance features, they are often applied in antenna array and base station designs of RF and microwave circuits. In the frequency range of 2.4-5.8GHz, wilkinson power splitters can provide relatively flat power distribution, while maintaining low insertion and reflection losses, ensuring high-quality signal transmission.

The basic principle of wilkinson power splitters is to distribute input signals to multiple output ports using wilkinson technology, while achieving power balance among all the output ports. Typically, wilkinson power splitters consist of a center-fed structure and multiple output port structures, where the power distribution ratio between them depends on geometric structures.

In summary, wilkinson power splitters can provide excellent signal transmission performance for wireless communication with multiple output ports, while possessing high reliability, ease of assembly, and simple structure features.
