It has been optimized and simulated by HFSS and microwave office software. The application of the method in design and co-simulation improves efficiency, especially for complex filters, and it greatly narrows the production cycle, thus saving cost. These excellent features, including small size, wide band, high isolation, low insertion make it a promising candidate in the future of wireless communication.
