TL;DR: This letter presents a radiation pattern verification system for low-frequency antennas in their operative conditions, e.g., on the ground, next to other elements, etc, using a properly equipped micro unmanned aerial vehicle (UAV) as a test source.

TL;DR: The prospects originating from the application of all-metal 3D printing to the manufacturing of high-performance microwave waveguide devices are reported on.

TL;DR: A successful measurement campaign has demonstrated that a UAV-mounted test source provides a means to accurately validate and calibrate the full-polarized response of an antenna/array in operating conditions, including consequently effects like mutual coupling between the array elements and contribution of the environment to the antenna patterns.

TL;DR: In this paper, the authors identify the new class of processes through which objects are built by selectively adding material, usually layer by layer, instead of subtracting material, as in conventional machining techniques like chemical etching, laser-cutting, milling, and electroerosion.

TL;DR: In this article, a waveguide polarizer exploiting two different phase shift phenomena is presented in which iris-type discontinuities are in fact introduced in waveguide structure having different propagation constants for the two principal polarizations.
