Most radio SETI (Search for Extraterrestrial Intelligence) projects concentrate on frequencies from 1.42 to 1.66 GHz.
Abstract: In this letter, a wideband dual-beam patch antenna and its array with compact size and high efficiency are proposed, analyzed, and measured. The antenna geometry and operational principle ...
Peter Delos, Technical Lead, Bob Broughton, Director of Engineering and Jon Kraft, Senior Staff Field Applications Engineer, all with Analog Devices. With the proliferation of digital phased arrays in ...
What Is RADAR? Radio Detection and Ranging is a system or device that uses electromagnetic radio waves to determine the range, velocity, and angle of the objects in the surrounding area. This system ...
Normative and mechanistic model of an adaptive circuit for efficient encoding and feature extraction
The brain represents information with neural activity patterns. At the periphery, these patterns contain correlations, which are detrimental to stimulus discrimination. We study the peripheral ...
Metasurface antennas have been proposed for computational imaging (CI) systems, which can reconstruct images without using mechanical scanning or large antenna arrays. In a CI system based on ...

Metasurface-based terahertz (THz) modulators, which carry information by changing the spatial pattern of the metasurface at every symbol time, are an important component to establish low-cost ...
Abstract: This letter discusses some of the challenges for realizing large millimeter-wave phased array antennas using multiple scalable arrays (tiles). The letter uses the radiation pattern ...
