Abstract
A novel double-ring resonator of the double square loop configuration is introduced to achieve the performance of the wideband bandpass filter. To obtain lower insertion loss (0.97 dB), deeper transmission zero level (35.4/34.6 dB), and wider bandwidth (43.22%), using the double square loop and aluminum nitride substrate are proposed. The transmission zeros and resonances are determined and studied in this article. Simulation and measurement results including surface current distributions and frequency responses are presented and discussed. It can be applied to 1.8 to 2.7 GHz high thermal conductivity systems.
