Abstract
A filtering device includes an isolation substrate including a first plane and a second plane, a micro-strip line deposited on the first plane of the isolation substrate for transmitting signals, and a ground metal layer deposited on the second plane of the isolation substrate for providing grounding. A meander-shaped resonating cavity is formed in an area of the ground metal layer corresponding to an area of the micro-strip line, for generating a rejection band on the micro-strip line.
