Dielectric Resonator
1.Introduction
A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction. This creates an internal electric field which redu ....etc

Resonator
A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonance frequencies, with greater amplitude than at others
It oscillates at specific frequencies because its dimensions are an integral multiple of the wavelength or half-wavelength at those frequencies
Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal
In physics and engineering the quality ....etc

H-Shaped Dielectric Resonator Antenna for UWB application




INTRODUCTION
The extremely wide spectrum of 3.1 to 10.6 GHz with 15 bands of bandwidth greater than 500 MHz and power limit less than -41.3 dBm/MHz announced by FCC for Ultra wide band. The release of this Spectrum has rapidly increased the research in UWB technology for communications, radar imaging, and localization applications . Radio systems based on UWB technology offer opportunities for tra ....etc

ABSTRACT

Balanced doubly suspended structure has been used earlier for very precise high Q resonators. But here we have used the unbalanced half section which is sputter deposited with a magnetic film. The central axis acts like a torsion wire of about a micron width and thickness. The outer arm deflects downwards about the torsi ....etc
