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 ...

So I've been familiar with the basics of polarization since forever, but I recently realized circular polarization is a mystery to me. I've heard of it in conjunction with eg satellite broadcasts, but ...

image: a, Schematic of the proposed all-in-one polarizer that can function at an arbitrary position on the Poincaré sphere by design based on a dielectric metasurface composed of dimerized nanopillars ...

All of the major antenna manufacturers were recommending full circular polarization (CP) to provide the best possible Mobile DTV coverage. Antenna manufacturers showed an interest in Mobile DTV at the ...

Researchers have designed a metasurface that can be continuously tuned from linear to elliptical birefringence, opening up the entire space of polarization control with just one device. This single ...

These days, when it comes to GPS devices the antenna is typically part of the package. But what better opportunity for [Pepijn] to learn how to make a GPS antenna from scratch for a badge add-on? A ...
