In this letter, a further miniaturization approach for the exiting MCR design extending analysis to 3D isotropic case. It is shown that the subwavelength resonance occurs when transversal permeability components have opposite signs. In this case, the rectangular cavity supports subwavelength resonance, and the width and length of such the rectangular cavity resonator can be in principle simultaneously...
In this paper, a novel RF-MEMS phase shifter based on a rectangle bridge-like coplanar waveguide (BCPW) structure is proposed. The signal line of the coplanar waveguide (CPW) has symmetrical saw-shaped structures under the MEMS bridges above which covers the BCPW bridge. The CST software is used for the modeling, simulation and optimization the model of phase shifter from 30 to 40 GHz. Simulation...
This paper describes a methodology for developing an effective electromagnetic compatibility (EMC) computer based technical support platform (TSP) system which is used for the analysis, prediction and design of system-level EMC. This computer-based TSP is integrated by EMC resource databases, specifications modules EMC design module, platform management module and EMC analysis tools. The main advantage...
In order to broad bandwidth and reduce back radiation, a novel microstrip antenna element operating at millimeter-wave band is proposed which is used H-shaped coupling slot feeding and adds parasitic patch methods. Then, using this antenna element, we design 2x2 microstrip antenna arrays and their feeding network. Comparing with traditional feeding network, H-shaped coupling slot feeding methods has...
A rectangular waveguide filled with uniaxial metamaterial is investigated in this presentation. The EM fields distribution of TE modes in such a rectangular waveguide are derived, and transmission characteristics are discussed. It is shown that the longitudinal component of the metamaterial permittivity tensor has strong influence on the direction of the phase velocity for TE mode waves. Particularly,...
A novel cylindrical conformal 2times2 microstrip antenna sub-array operating at millimeter-wave band is proposed.. A planar array element with an H-shaped coupling slot is investigated for its bandwidth feature and radiation performance. Compared with conventional microstrip antenna array, a planar 2times2 arrays is designed, and the results of comparison illustrates that the proposed design has less...
In this paper, an improved miniaturized cavity resonator (IMCR) dependent on double negative metamaterial (DNG) and epsilon-negative material (ENG) layers is designed and optimized. The length and width of the IMCR are simultaneously shortened to the half of a conventional cavity resonator. The IMCR is numerically simulated, results show that the resonance phenomenon in the IMCR is observed clearly,...
This article discusses the near field properties of the horizontal dipole radiation in the presence of a lossless metamaterial sphere. Based on the approach of Greens function, under different geometrical and electromagnetic parameters, the near field properties are investigated. It could be seen that in the metamaterial sphere, the focusing" phenomenon is observed. It is in consistent with the...
