Reçu le 9 octobre 1972, révisé le 24 janvier 1973) Résumé. 2014 Des mesures du coefficient de surtension Q ont été réalisées sur trois types de résonateurs microbandes à substrat d'alumine : ligne ouverte de longueur 03BB, anneau de longueur 3 03BB et disque. La comparaison des valeurs expérimentales et théoriques est satisfaisante. Pour la dernière structure, un Q0 de 900 a été obtenu.Abstract. 2014 Unloaded Q factor measurements have been made of one-port integral-wavelength open line, a three-wave circular ring, and one empty disc resonator on an Al 2O 3 substrate. Theoretical and measured values are compared. Q0 factors up to 900 have been measured in the disc resonator.

“…Therefore, the -factor should decrease with frequency increase. The measured -factors of fundamental modes of circular microstrip resonators at room temperature are also much smaller than for the studied WGR: about 100 at GHz [23] and from 80 to 130 at GHz [24]. Hence, even without the microgap, the proposed WGR demonstrates a -factor approximately five times higher than known circular microstrip resonators.…”

Whispering gallery modes (WGMs) were exited in a new type of microstrip circular resonator formed under a conducting disc placed directly on or above a continuous dielectric layer. Resonance frequencies, quality factors, and distributions of the microwave field for different WGMs have been studied numerically and experimentally as a function of distance between metal and dielectric. An unloaded -factor up to 890 was obtained using polished copper disk and layer of single crystalline sapphire. Generalization of the known condition of the excitation of the WGMs in a dielectric medium is proposed.

“…As the bandwidth of microstrip patch resonators and antennas around their operating resonance frequencies is known to be very narrow 1, it is important to develop accurate algorithms for the computation of those resonance frequencies. A number of sophisticated numerical techniques have been developed and used to analyze circular microstrip antennas 11 or resonators 12. The best ones are the method of moment 13, the finite‐element method 14 and the finite‐difference time‐domain 15.…”

SUMMARYThe purpose of this study is the formulation of a wave concept iterative process for the analysis of the microwave planar circuits printed between two dielectric mediums in a cylindrical metallic box. This method is based on the transverse wave formulation. It also uses the Hankel Transform to express the integral relation in a spectral domain. An example of circular patch has been studied and the obtained results validate the new approach. The good agreement between the simulation results and the experimental published data justifies the design procedure and validates the present analysis approach.
