To John Schadler, director of Advanced Antenna Systems Development at SPX Communication Technology (formerly Dielectric), the future success of mobile DTV depends largely on the service reliability ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ...

An electromagnetic wave or signal traveling from “here” to “there” has an electrostatic field component that we call its E-field and whose direction we assign as the signal’s polarity. Often, the ...

Unless you work for the government or a large corporation, constrained designs are a fact of life. No matter what you’re building, there’s likely going to be a limit to the time, money, space, or ...

Standard whip or rubber duck antennas are extremely common due to their low cost and design simplicity. They work very well for long range transmission when the orientation doesn’t change and ...
