Presenting the 1st prize winner in the TI LDC1000 inductive sensor design contest. High gain beam scanning arrays are usually implemented using phased antenna arrays or mechanically controlled ...

In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

Editor's note: To view a PDF version of this article, click here. Last month's column introduced the antenna pattern and arrays. This month's column will describe the idea of the linear antenna array, ...

If you could squeeze two or three times more cellular telephone conversations into the same amount of bandwidth, how much would that be worth? To most wireless companies, the answer is, millions of ...

The need for significant improvements in radar continues to be an ongoing concern for the Department of Defense (DoD). One of the most impressive developments addressing this need is a high-resolution ...

IEEE Spectrum – new antennas based on metamaterials, though, may soon rescue Web-addicted travelers from expensive connections in the air and elsewhere, and a group at the patent-licensing firm ...

Future photonic circuits with the capability of high-speed data processing at optical frequencies will rely on the implementation of efficient emitters and detectors on the nanoscale. Towards this ...

Within a few years, researchers at the United Kingdom’s University of Birmingham could provide a new beam steering antenna usable with ultra-high radio frequencies that may be critical to future ...

Why a reflective array offers benefits compared to active elements in a high-density array. How a binary phase-control scheme is used in place of conventional phasing for extremely low power, ...
