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 torsion ....etc

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

Microstrip antenna for mobile phones
There are several types of microstrip antennas used in telecommunication. These are also known as printed antennas. The microstrip antenna radiator shapes which xcare commonly seen are square, rectangular, circular and elliptical but it is also posible to create radiator of any continuous shape. mobile radio communications devices extensively use this antenna because of their low profile, are mechanically rugged and can be conformable. They are also relatively inexpensive to manufacture due to the ....etc

ABSRTACT

The delayed resonator, as a tunable active vibration absorber with an emphasis on the design features. This technique uses a control that has a time-delayed feedback of the absorber mass displacement. The substance of this process is in that the absorber completely removes oscillations from the harmonically excited primary structure. Seminal features of this method are the excitation frequency range can vary over a semi-infinite interval, and the absorber can be tuned in real ....etc

Design and development of X-band micro strip patch antenna

Introduction

In high-performance aircraft, spacecraft, satellite and missile applications, where size, weight, cost, performance, ease of installation, and aerodynamic profiles are constraints, low profile antennas may be required. These antennas should have low profile, conformable to planar and non-planar surfaces, simple and inexpensive to manufacture using modern printed-circuit technology, mechanically robust when mounted on rigid surfaces, compatible with MMIC designs, and w ....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 transmission of high data r ....etc
