Mutual Coupling Reduction of Microstrip MIMO Antenna Using Microstrip Resonator

Wireless Personal Communications, 2020
In this paper, we describe a novel approach to reduce the mutual coupling between two adjacent microstrip MIMO antennas by using resonator structure. The basic microstrip patch antenna is operated at 5.9 GHz, and the center to center distance between two adjacent antenna elements is kept 0.46λ0.

A New Planar Microstrip Resonator for Microwave Circuits: The Quasi-Fractal Microstrip Resonator

29th European Microwave Conference, 1999, 1999
a new shape for microwave planar circuits using the self-similarity of the fractal geometry is presented. This new shape allows the generation of numerous resonant frequencies for this microwave planar resonator due to the surfaces encasilng. The resonant frequency assessment can be useful to concept specific filters or wide frequency band matching ...

Resonance frequency of a rectangular microstrip patch

IEEE Transactions on Antennas and Propagation, 1988
The microstrip-patch resonant frequency problem is formulated in terms of an integral equation using vector Fourier transforms. Using Galerkins's method in solving the integral equation, the resonant frequency of the microstrip patch is studied with both Chebyshev polynomials and sinusoidal functions as basis functions.

Q-factor of tuned microstrip resonator

Radioelectronics and Communications Systems, 2016
The paper presents research of quality factor in the micro-mechanically tunable microstrip resonator and its change in response to tuning. In the presented design unloaded quality factor increases about 10% during tuning due to reduction of dielectric loss in substrate’s medium and ohmic loss in metal electrodes.

Resonance of the axial-symmetric modes in microstrip disk resonators

Journal of Mathematical Physics, 1980
Three methods have been used to calculate the resonant frequencies for the axial-symmetric modes in the microstrip disk resonators which also have the application as radiating antennas. The variational Galerkin’s method provides the most accurate result for the estimation of both the real and imaginary parts of the resonant frequency shifts with ...

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.

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.

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.

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.
