Abstract

It designs a coaxial cavity band pass filter

achieving small size and high isolation with a new cross-coupling structure. 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.
