Abstract

The invention discloses a reconfigurable frequency selection structure using a temperature-sensitive resistor, which includes a dielectric substrate, the cross section of which is a square, and a square copper foil block attached to the upper surface of the dielectric substrate. A regular hexagonal annular groove is provided, and the regular hexagonal annular groove divides the square copper foil block into a first copper foil area located outside it and a second copper foil area located inside it, the first temperature-sensitive resistor, the second The temperature sensitive resistor, the third temperature sensitive resistor and the fourth temperature sensitive resistor are evenly arranged between the first copper foil area and the second copper foil area, and the working temperature range of these four temperature sensitive resistors is minus 5 degrees Celsius to Positive 300 degrees Celsius; the advantage is that it can realize bandpass characteristics in multiple frequency bands, and when applied to frequency selective surfaces, it can reduce the design workload of frequency selective surfaces and reduce the design and processing costs of frequency selective surfaces.

Description

technical field [0001] The invention relates to a frequency selection structure, in particular to a frequency selection structure using a temperature-sensitive resistor to realize reconfigurable passband. Background technique [0002] For a long time, with the continuous innovation and development of various communication technologies, the spectrum resources are fixed, which leads to more and more tight spectrum resources. Therefore, improving the utilization of spectrum resources has always been the top priority of many researchers. Among them, the bandpass structure has attracted the attention of researchers, and some research results have been obtained. Common bandpass structures are mainly realized based on microstrip line structure, integrated waveguide structure or cavity structure. The bandpass structure based on the microstrip line structure forms the bandpass characteristic by laying a microstrip line with a certain structural shape above the dielectric substrate; ...
