Abstract
(EN)
A filtering antenna, characterized by comprising a radiating structure, a filtering structure, and a feeding structure. The radiating structure is formed by multiple antenna units which are stacked up and down, the filtering structure is formed by multiple resonant cavities which are stacked up and down and are sequentially coupled and communicated, the filtering structure comprises an input end and an output end, the radiating structure and the filtering structure are stacked up and down and are electrically connected to each other by means of the output end, one end of the feeding structure is electrically connected to the input end of the filtering structure, and the other end of the feeding structure is used for being externally connected to a power supply. According to the present invention, the size is effectively reduced by means of a stack structure so as to implement miniaturization, multistage SIW cavity cascading is utilized for obtaining broadband filtering performance, and interference of an out-of-band spurious signal can be effectively inhibited in a broadband frequency range.
