MUTUAL COUPLING ANALYSIS USING FDTD FOR DIELECTRIC RESONATOR ANTENNA REFLECTARRAY RADIATION PREDICTION

Mutual Coupling Analysis Using Fdtd for Di- Electric Resonator Antenna Reflectarray Radiation Prediction

A simulation technique based on Finite-Difference TimeDomain (FDTD) is used to analyze mutual coupling effects in reflectarray environment. The neighbouring element method has the ability to analyze actual non-identical reflectarray unit-cell accurately compared to the traditional Floquet simulation which assumes all unitcell is identical. It is also found that the nearest neighbouring unit-cel...

Analysis of Dielectric Resonator Loaded Antenna

This thesis presents design of dielectric resonator loaded antenna for wireless applications. The design is a Different shape Dielectric Resonator Antenna (DRA) using different material for wireless applications. Here the DRA is excited by conformal patch connected to co-axial feeding which is an effective feed mechanism and more efficient in energy coupling than other types of feeding techniqu...

Dielectric Resonator Antenna - Possible Candidate for Adaptive Antenna Arrays

Future base stations for Spatial Division Multiplex Access (SDMA) will utilize adaptive antenna arrays, capable of identifying the direction of the incoming signal and steering the transmitted beam in appropriate directions. The radiating elements that have been thus far considered for building the antenna array are typically wire dipoles or microstrip patches. This tutorial paper describes a n...
