On the Study of Resonance Splitting in Microstrip Ring Resonators

1990 20th European Microwave Conference, 1990
An equivalent circuit model based on transmission line theory has been analysed to investigate the resonant behaviour of an asymmetrically coupled microstrip ring resonator. Resonance splitting is theoretically predicted and experimental work carried out verifies this phenomenon.

Analysis of Microstrip Resonators

IEEE Transactions on Microwave Theory and Techniques, 1974
An accurate and efficient method was developed for computing the resonant frequencies of microstrip resonators. The formulation of the problem was carried out rigorously using the full-wave analysis rather than the quasi-static approximation. The characteristic equation was derived using Galerkin's method applied in the Fourier transform domain.

Microstrip array in open resonator

Proceedings of Xth International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory, 2005
Possibility of excitation of the lowest mode oscillations in a semi-symmetric open resonator (OR) using 4 element microstrip array (MSA) is examined. MSA properties at 10 GHz frequency are calculated. Experimental curves of loaded Q-quality and resonant gain as a function of distance between the mirrors of the OR, excited by the MSA, and an aperture ...

Coupled Microstrip Disk Resonators

IEEE Transactions on Microwave Theory and Techniques, 1980
The coupling between microstrip disk resonators is investigated analytically and experimentally. The interaction between the printed disks is modeled by a gap capacitance, which is computed by solving the corresponding electrostatic problem. An integral equation is used to determine the nonsymmetric charge distribution on the disk resonators. Numerical

A dielectric resonator on a microstrip antenna

Proceedings of IEEE Antennas and Propagation Society International Symposium, 2002
As long as the resonant frequency of a stand-alone parasitic element is close to but not equal to that of the active microstrip antenna, mutual coupling effects between them could alter the characteristics of the entire system. Satisfactory results are observed when the passive element is placed on top of the patch antenna.

Analysis of Triangular Microstrip Resonators

IEEE Transactions on Microwave Theory and Techniques, 1982
An isosceles triangular microstrip resonator is analyzed with the full wave formulation of the spectral domain technique. For a given apex angle and triangle height, the resonant frequency is evaluated from the numerical solution of the determinantal characteristic equation, obtained by neglecting the transverse current density.

Microstrip U-shaped resonators

Radioelectronics and Communications Systems, 2012
Influence analysis of U-shaped microstrip resonators’ parameters and parameters of dielectric substrate on resonant frequencies and unloaded quality-factor of resonators is conducted. Three kinds of U-shaped resonators are considered which differ in operation modes at the resonator’s ends: short-circuit or no-load. It is revealed that in cases of small

Microstrip resonances in superconducting circuits

IEEE Transactions on Magnetics, 1987
Josephson junctions connected to high Q microstriplines display current-steps which we attribute to standing wave resonances. The step voltages of the resonances depend on sample geometry and correspond to frequencies at which the loaded microstrip is resonant.

Microstrip resonators on anisotropic substrates

IEEE Transactions on Microwave Theory and Techniques, 1992
The spectral domain method is applied to study shielded microstrip resonators printed on anisotropic substrates. A Green's function that takes into account the dielectric anisotropy effects is derived through a fourth-order formulation. Galerkin's method is then applied to form the characteristic equation from which the resonant frequency of the ...

Microstrip and resonator type feeds

1994
One of the difficulties with microstrip antennas is the resistive losses due to the conductor and its substrate, which become significant at high frequencies. In an attempt to reduce these losses, Kishk et al. have studied the use of dielectric resonators as a candidate for reflector feeds and in lieu of microstrip patches. Feed performances similar to
