A frequency-tunable coplanar waveguide series capacitor resonator

Abstract

The present invention is a coplanar waveguide series capacitor resonator with adjustable frequency. The resonator includes a first layer of dielectric material A, a second layer of dielectric material B and a third layer of dielectric material C. In the first layer of dielectric material The material A is provided with a first metal layer A1, a second metal layer A2, a third metal layer A3, a fourth metal layer A4 and a fifth metal layer A5, and the second layer of dielectric material B is an adjustable dielectric constant Dielectric material, the ground plate metal layer C1 is printed on the third layer of dielectric material C, the input end of the resonator is on the left side of the first layer of dielectric material A, and the output end of the resonator is on the first layer Right side of dielectric material A. In the present invention, by changing the dielectric constant of the dielectric material B, the boundary conditions between the first layer of dielectric material A and the second layer of dielectric material B are changed, thereby changing the resonant frequency point of the resonator, and realizing an adjustable frequency Coplanar waveguide series capacitive resonator.

Description

technical field [0001] The invention belongs to the field of electromagnetic field and microwave technology, and in particular relates to an adjustable frequency resonator, in particular to an adjustable frequency coplanar waveguide (CPW) series capacitor resonator. Background technique [0002] With the rapid development of the wireless communication industry, frequency resources are becoming increasingly tight. In order to improve the utilization of spectrum resources, spectrum technologies such as spread spectrum, frequency hopping, and dynamic frequency allocation have been widely used. Because of its compact structure, easy system integration, and low power consumption, frequency bandpass filters have gradually become a research hotspot. As one of the key components of microwave receivers and electronic countermeasure systems, tunable microstrip filters are also increasingly popular. Attention, in recent years, the realization of the frequency modulation of the filter i...
