Antipodal Vivaldi antennas (AVAs) have emerged as a critical component in advanced wireless communication and sensing systems, owing to their inherently wide bandwidth, high gain and stable radiation ...

VIVALDI. No, you aren’t reading an article in Gramophone. This happens to be the name of a particular kind of broadband antenna, which is particularly useful at microwave frequencies and for ...

While you might think of radar pointing toward the skies, applications for radar have found their way underground as well. Ground-penetrating radar (GPR) is a tool that sends signals into the earth ...

A radar can be used to locate a buried object. Therefor the radar should operate at low frequencies to be able to penetrate the medium the object is buried in and it should have a high spatial ...

Scientists develop a novel CMOS-based transceiver for wireless communications at the 300 GHz band, enabling future beyond-5G applications. Their design addresses the challenges of operating CMOS ...
