Journal Article
A fast optimization technique for comb-line filters based on dielectric loading
2025
Overview
In the field of electronic information science, with the continuous advancement of signal processing technology, filtering technology has become particularly important due to its ability to effectively suppress noise and extract useful information. This article focuses on exploring an innovative method for rapid optimization of filters. By designing a hollow cylindrical dielectric ceramic and combining it with traditional inductive structures, the bandwidth and return loss characteristics of intelligent filters at various frequencies could be quickly controlled. Simulation results show that by loading the dielectric ceramic, the bandwidth of filter 1 is reduced by an average of 20%, the return loss at low frequencies is increased by an average of 3 dB, and the return loss at high frequencies is reduced by 5 dB. Simulations were conducted on two different structures of filters, and the results showed that the optimization design technique has good applicability.
