Microstrip Band-Pass Filter using 3 Serial Arranged Elements Artificial Dielectric Materials based on Open Split-Ring Resonator

摘要

In this paper, we will discuss the process of designing and fabricating a microstrip band-pass filter using artificial dielectric materials based on OSRR (Open Split-ring Resonator) in frequency range 2 - 4 GHz. In meeting the increasingly high filter requirements as technology develops specifically for S-Band radar, this research will make a microstrip filter using 3 elements based on OSRR. The results of filtering will be observed from the result of filter responses such as frequency, power losses, and BW parameters. The design observed using simulation methods by changing distance of each OSRR elements and realizing the results of the filter design in physical realization. The results of physical realization are then measured and compared with the simulation design results. From measurement obtained Return loss, Insertion loss, and bandwidth as 27 dB, -0.2 dB, and 500 MHz respectively at frequency 3.875 GHz.
