We're about 117 days in Amazon's semi-annual sale, and we've ID'd lots of top-notch menswear from Bezos' Big Site of Stuff.

In this article, two novel efficient leaky-wave antennas (LWAs) with stable radiation patterns operating in the 60 GHz band are proposed. The LWAs are implemented in groove-gap waveguide (GGW) ...

In this communication, we propose a new multiple-polarization vortex wave generator based on a folded transmitarray antenna (FTA) with high-gain and low-profile characteristics. The proposed vortex ...
