Abstract

The invention discloses a W-band high-temperature superconducting plane filter and a bandwidth and external Q value adjustment method therefor. The filter comprises a substrate, a high-temperature superconducting film formed on the substrate, and a circuit pattern formed through the high-temperature superconducting film. The circuit pattern comprises a filter main body with the passband being at the W band, and circuit points formed at the periphery of the filter main body. The circuit points and the filter main body structure form trenches through laser etching, thereby enabling the filter main body and the circuit points to form a coplanar waveguide structure. The filter provided by the invention effectively avoids a higher-order mode of a millimeter wave band designed on a high-dielectric-constant high-temperature superconducting dielectric substrate. A resonator is a 1/4 waveguide wavelength strip-shaped resonator, and can achieve better coupling and resonance characteristics at the W band. The filter has excellent performances on higher-order mode inhibition, saves a high-temperature superconducting film material, weakens the processing process of a high-temperature superconducting filter, and reduces the processing cost.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave passive devices, and in particular relates to a W-band high-temperature superconducting planar filter and a method for adjusting its bandwidth and external Q value. Background technique [0002] In recent years, with the rapid development of wireless communication technology, spectrum resources in the radio frequency and microwave bands have become increasingly scarce, which has led developers to focus on higher frequency bands—millimeter wave bands. Due to the impetus of market demand, millimeter wave technology has received great attention and rapid development, especially in radar, navigation guidance and short-range high-speed communication, the advantages of millimeter wave are particularly prominent. Compared with radio frequency and microwave systems, millimeter wave has shorter wavelength and more abundant spectrum resources, which can provide better accuracy and reso...
