Title
A Frequency-Tunable SRR-Adopted Two-Pole Waveguide Filter Operatingbelow the Cutoff Frequency
Description
This research was supported by Basic Science Research Program throughthe National Research Foundation of Korea (NRF) funded by the Ministryof Education (no. 2015R1D1A1A01059175) and by research fund from ChosunUniversity in Korea, 2016.
abstract
A frequency-tunable filter operating below the cutoff frequency of a metallic hollow waveguide is proposed, which has two-pole bandpass characteristics and incorporates a split-ring resonator (SRR). The tuning procedure is achieved by inserting two metal screws. The screws adjust the magnetic-field passing through the center of the SRR. The effect of SRR orientation was investigated and the optimum orientation proposed. Our results indicated an operating frequency range of 2.0 to 2.35 GHz, which is lower than the cutoff frequency of the waveguide of 4 9 GHZ by more than 2.55 GHz. The proposed filter could be utilized for communication, such as software-defined radio (SDR) systems.
