TWO-ELEMENT COMPACT ANTENNAS DECOUPLED WITH A SIMPLE NEUTRALIZATION LINE

Compact Antennas — An overview

A Simple Line Element to the Dilaton Gravity

The metric to the two-dimensional dilaton gravity can be writen in an alternative form, similar to the two-dimensional Schwarzschild metric, and allow us the identification of some quantitiies with those equivalent in the Schwarzschild solution. This new form, howewer, presents a non-physical singularity at the horizon in the same way that in the realistic four dimensional case. We show a proce...

Towards tetrahedral meshing with decoupled element and boundary constraints

In tetrahedral mesh generation, the constraints imposed by adaptive element size, good tetrahedral quality (shape measured by some local metric), and material boundaries are often in conflict. Attempts to satisfy these conditions simultaneously frustrate many conventional approaches. We propose a new strategy for boundary conforming meshing that decouples the problem of building tetrahedra of p...

Meander Line Antennas

SkyCross' state-of-the-art antennas are smaller and can be embedded directly within the handset. In addition, they feature better gain and improved efficiency, resulting in longer battery life than other handsets currently available on the market today. Furthermore, MLA technology allows engineers to design ultra broadband antennas capable of operating at multiple frequencies and in a variety o...

Compact Antennas with Reduced Mutual Coupling for Wireless Sensor Networks

Printed sinusoidal monopoles are a type of meander line antennas, with smooth curve structure and enhanced performance, suitable for building compact multi-element antennas (MEAs). The antennas described here were designed at 2-3 GHz to meet the size and bandwidth constraints of multimedia sensor networks. Their performance was characterized in terms of electrical size, bandwidth, and broadband...
