Abstract
The present invention provides a filter antenna including a first resonant cavity and a second resonant cavity which are stacked from top to bottom and in coupling communication with each other, an antenna unit provided on a side of the first resonant cavity facing away from the second resonant cavity, and a feed structure provided in the second resonant cavity. The present invention integrates a filter with an antenna to ensure the performance of the filter antenna by using a SIW cavity filter, thereby effectively suppressing interference from out-of-band spurious signals. In addition, the stacking structure of the antenna and the filter effectively reduces a volume to achieve miniaturization, and the antenna structure is optimized in a compact environment.
