A Rectangular Dielectric Resonator Antenna (RDRA) is theoretically analyzed using the Conventional Dielectric Waveguide Model (CDWM), numerically simulated using the High Frequency Structure Simulator (HFSS) based on the Finite Element Method (FEM) software package and experimentally investigated with the consideration of the fundamental mode TE 111. Antenna parameters under investigation inclu...

Microstrip patch antennas are well known for their advantages in terms of small weight, low profile and ease of manufacture. However, the main limiting factor in implementing these antennas in many applications is their low impedance bandwidth (typically 2-3%). One popularly used technique of enhancing the bandwidth is to use multi-layered microstrip[1,2]. The most widely accepted structure in ...

The following work reports the design, numerical, analytical and simulation characterization of an Aluminum Nitride MEMS resonator. The paper offers a comparison of rectangular plate MEMS resonator (length extensional and width extensional mode shapes) and ring shape MEMS resonator. It also demonstrates the contour Eigen modes of resonators and their equivalent electric circuit model (BVD). Fur...

— In this paper, a novel notch resonator is proposed based on Rectangular Split Ring Resonator (R-RSS) element. We represented the electrical characteristics for R-SRR elements coupled with microstrip line, and measured result is compared with electromagnetic simulation (HFSS) result. We also solved equivalent circuit for R-SRR element, and also discussed influences of change structural paramet...

An investigation of the effect of resonator dimensions on nonlinear standing waves in shaped resonators is conducted. Simple forms of the shear viscosity term in the momentum equations are developed for an axisymmetric (2D) resonator and a low aspect ratio rectangular (3D) resonator. The cross sections of the resonators are exponentially expanded and the one-dimensional wave equations are solve...

A compact center shorted rectangular microstrip antenna has been discussed. The bandwidth enhancement of the compact MSA has been realized using gapcoupled multi-resonator technique, which gives the bandwidth of more than 20%.
