Abstract
The invention relates to a substrate integrated waveguide adjustable filter. The substrate integrated waveguide adjustable filter comprises a resonant cavity and a plurality of first adjustable devices, wherein the resonant cavity comprises a first metal layer, a dielectric layer and a second metal layer, the dielectric layer is clamped between the first metal layer and the second metal layer, a metal through hole is formed in the interior of the resonant cavity, the metal through hole passes through the edge of the first metal layer, the edge of the dielectric layer and the edge of the secondmetal layer, and a rectangular cavity is surrounded; a gap is formed in the first metal layer along the inner side edge of the rectangular cavity; the first adjustable devices are distributed at different positions inside the rectangular cavity, and are used for controlling the resonant frequency of the resonant cavity. According to the substrate integrated waveguide adjustable filter, the gap isformed in the first metal layer, so that the upper metal layer and the lower metal layer of the resonant cavity are coupled, and the resonant frequency of the resonant cavity is greatly reduced; andwhen the substrate integrated waveguide adjustable filter with same center frequency is designed, the transverse area of the substrate integrated waveguide adjustable filter disclosed by the inventionis smaller, and the integration level is improved.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a substrate integrated waveguide tunable filter. Background technique [0002] With the rapid development of modern wireless communication systems and the increasing advancement of military information technology, spectrum resources have become increasingly scarce, and electronic warfare has become increasingly fierce. In order to improve the utilization of spectrum resources and the security of military information, spectrum technologies such as multi-passband, spread frequency hopping and dynamic frequency allocation are widely used, which greatly promote the development of tunable microwave devices. Tunable devices can not only reduce the number of devices required for different frequency bands in the system, realize the miniaturization of the system, but also meet the requirements of multi-band, multi-performance, and anti-interference in modern communications. Therefor...
