Sensitivity Analysis of Rectangular DRA,DRA. The resonant modes are formed when realized with excitation. The resonant frequency solution is worked with MATLAB and HFSS software. When these dimensions are changed, resonant frequency of RDRA also changes. Variance method has been tried out to evaluate error.

Mathematical Analysis of RDRA Amplitude Coefficients,onfinement of energy within the resonator. Certain field distributions or modes will satisfy Maxwell’s equations and boundary condition. Mathematical solution to get amplitude coefficients .. along with its phase coefficients has been obtained. These are also known as eigenvector.

RDRA Angular Excitation Mathematical Model and Resonant Modes,f a RDRA are dependent on shape, DRA volume and excitation. The excitation current can be defined in terms of magnetic vector potential “.” based on applied current densities “.”. This “.” can be expressed in terms of . and . fields or as “.” Poynting vector.

Inhomogeneous Permittivity, Permeability, and Conductivity Solution in Rectangular DRA,ed “the waveguide modes” and are of the form cos–sin. Depending on the nature of wall surfaces (PEC or PMC), four possible linear combinations can appear (cos–sin, sin–cos, sin–sin, and cos–cos). The discrete modes enable us to visualize the resonator as collection of L, C oscillators with different ., . values.

Case Studies,lar DRA using ceramics such as eccostock-500. Nomenclature and parameters obtained have been mentioned below the each figure. Emphasis is also given on geometry of antennas and their experimental results. The experimental results have been obtained under specific environmental conditions i.e. anechoic chambers.
