Abstract
The application discloses a hybrid embedded single-cavity multi-mode patch resonator and filter, and the resonator comprises a first metal layer, a first dielectric substrate layer, a second metal layer, a second dielectric substrate layer and a third metal layer which are sequentially arranged from top to bottom, a first blind hole array is arranged on the second metal layer, the second metal layer, the second dielectric substrate layer, the third metal layer and the first blind hole array form a quarter-mode substrate integrated waveguide resonant structure, and a second blind hole array is arranged on the first metal layer. Through the hybrid embedded resonant structure design, the radiation loss is significantly suppressed while the unloaded quality factor is maintained, so that the insertion loss of the filter is reduced, and the overall electrical performance is improved.
