Dual-Band Filter Using Non-Bianisotropic Split-Ring Resonators

Abstract

Abstract-This work proposes the use of Non-Bianisotropic Split Ring Resonators (NB-SRRs) as building blocks for dual-band response filters. Design parameters will be evaluated in order to characterize coupling mechanisms for both the particle and filter structure. A ready-to-use dual-band filter for a multiconstellation Galileo/GPS global positioning receiver is manufactured in order to validate and test the proposed design. The device transmission response measurement agrees with both circuital and electromagnetic simulations, as well as with theoretical insertion losses, which are 2.4 dB and 3.5 dB at center passbands for L 5 and L 1 bands respectively.

Compact Multi-Band Filter Based on Multi-Ring Complementary Split Ring Resonators

“…In particular, split-ring resonator (SRR) can be used as a basic particle for the design of stopband negative permeability structure [6]. The possibility of designing bandpass and band-reject filters using split ring resonator has been demonstrated in various studies [7][8][9]. In 2004, a stopband microstrip line based on complementary split ring resonators (CSRRs) was fabricated by Falcone et al [10].…”

A Novel Triple Passband Filter Design Method Based on Stepped Impedance Resonators

“…Resonators with controllable second and third harmonics and stubloaded resonators have been used to generate three passbands. And some other design procedures about multi-band filter have been discussed in paper [7][8][9][10][11][12][13].…”

“…Multi-band filters become quite popular. Therefore, they had been widely studied in several papers [2][3][4][5][6][7][8][9][10][11][12][13]. In [2], a tri-band filter was designed using three sets of resonators with a common feed circuit, but it has a large size due to a large number of resonators.…”

“…΄ Αλλες παραλλαγές αποτελούν ο ανοιχτός SRR (open SRR) [110], που μπορεί να χρησιμοποιηθεί ως φίλτρο σε διατάξεις γραμμών μικροταινίας, ο συντονιστής σπείρας δύο ή τριων στροφών (two-/ three-turn spiral resonator) [111], ο μη διανισοτροπικός SRR (non-bianisotropic SRR, NB), που αποτελεί μια εναλλακτική αντί του BC-SRR. [112], και ο ηλεκτρικός συντονιστής LC (electric-LC, ELC) [113], που σε αντίθεση με τους προηγούμενους συντονιστές, οδηγεί στην ανάπτυξη αρνητικής διηλεκτρικής σταθεράς. Εκτός από τον συντονιστή ELC, υπάρχουν και άλλοι συντονιστές που εμφανίζουν αρνητική διηλεκτρική σταθερά.…”
