Antennas and Feeders

Geometric design of part feeders

Preface This thesis considers problems derived from industrial engineering, and treats them in a rather theoretical setting, called ªcomputational geometryº. This work has been carried out within the research group of Mark Overmars, which is centered around applied algorithms, i.e. solving problems that are inspired by practical implications. My ®rst introduction to computational geometry was v...

Preliminary design analysis of linkage feeders.

In 1962 the Committee on Prosthetics Research and Development authorized a survey of current orthotics research and development in a number of selected centers as an initial step in a proposed orthotics evaluation program. A prime purpose of the survey was the identification of orthotic devices and procedures as suitable subject matter for the evaluation program. One of the devices selected as ...

Coupling Effects and Performance of Loran Transmitter Antennas

It is known that if a conductor resides in the neighboring of an antenna with a small distance relative to the wavelength, it induces a reverse current on the conductor. This paper involves the unavoidable coupling effects on some common types of LF antennas, due to the large wavelength in this frequency band. In particular, after some discussions about top-loaded antennas, the coupling effect ...

Probe-Fed Rectangular Dielectric Resonator Antennas,Theoretical Modeling and Experiments

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...
