Applying the Slow-wave Effect in the Design of a Compact Antenna

A novel method to design a compact antenna has been proposed. The shorting and feeding positions are located on both sides of the designed antenna, respectively; therefore, it is called a planar double inverted L antenna (PDILA). According to measured ...
Recent developments in most consumer electronic products is toward miniaturization. The technology of integrated circuits is widely applied in the field of communication baseband modules and radio frequency modules to make communication products smaller in size. On the contrary, the technology of integrated circuits is difficult to use to...

First Generation High Voltage Vertical FET

Radio Frequency (RF) power amplifiers play a critical role in a broad range of wireless applications, including infrastructure for mobile devices and cell phones, broadcasting and medical equipment, satellite and military communications, emergency radios, and radar. Increasing demands on overall system performance, in turn, translates into added pressure on...

Optimization of a C Band Pulse Altimeter

In this paper parameters of an old technology altimeter are discussed and then after deriving the measure of quality factor (height measurement accuracy), suitable solutions for improving the technology, namely decreasing its peak power (from 62.5w to10.9w) so to improve its LPI characteristics while maintaining its performance quality are...

Analysis and Design of a Linearly Tapered Slot

1. Introduction The planar end fire tapered slot antenna (TSA) is a novel technique and is presently quite new [1], this has been less studied theoretically with little information or analysis results available in journals and literature today. These types of radiating structures find wide applications [2] vis-à-vis: as...

Ultra-Wideband Technology and Test Solutions

Introduction UWB technology is quickly gaining acceptance as a wireless technology with outstanding characteristics. To understand UWB, we begin with a look at its origins and its growth to date. History Early radios like Guglielmo Marconi’s spark gap design (1896) marked the beginning of Impulse Radio (IR) communications. Inspired...
