Problems solved by technology

Epoxy resin is used in the field of high temperature protection materials because of its good bonding strength, low shrinkage rate, good electrical insulation, and low expansion rate. However, epoxy resin has poor thermal conductivity, brittleness and heat dissipation. However, the shortcomings such as poor performance cannot be really applied to the field of thermal conductivity materials.

Abstract

The invention relates to a filter, and particularly relates to a microstrip patch filter. The microstrip patch filter comprises a filter cavity, an outer casing and an inner casing, wherein a ventilation pipeline is arranged in the outer casing, a heat dissipation layer is arranged in the inner casing, a heat absorption layer is arranged on the inner surface of the heat dissipation layer, two fixed cavities are arranged on both sides of the outer casing, a microstrip patch is fixed above the fixed cavities, two ventilation valves are arranged under the fixed cavities and are used for controlling the incoming and outgoing of gas in the ventilation pipeline, a groove is formed between the fixed cavities and the filter cavity, a through-line pipe communicated with the filter cavity and the microstrip patch is arranged in the groove, and a base is also arranged at the bottom of the filter cavity. The filter provided by the invention is simple in structure, performs combined heat dissipation by using the heat absorption layer, the heat dissipation layer, the ventilation pipeline and other methods, and can greatly enhance the heat dissipation performance of the filter.

Description

technical field [0001] The invention relates to a filter, in particular to a microstrip patch filter. Background technique [0002] A filter is a radio frequency device that passes useful signals without attenuation as much as possible and attenuates useless signals as much as possible; it is generally installed in the signal transceiver device or circuit part of communication equipment to realize the selection of communication equipment signals. Generally, the filter is mainly composed of a filter cavity and a cover plate. There are multiple resonant rods in the filter cavity. One end of the tuning screw penetrates the cover plate and is opposite to the resonant rod. The adjustment tool adjusts the distance between the tuning screw and the resonant rod. The distance between them to achieve the required RF index. [0003] A microstrip filter is a device used to separate microwave signals of different frequencies. Its main function is to suppress unwanted signals so that th...
