The Use of 3D Printing Technology for Manufacturing Metal Antennas in the 5G/IoT Context
(Sensors (Basel), 2021)
With the rise of 5G, Internet of Things (IoT), and networks operating in the mmWave frequencies, a huge growth of connected sensors will be a reality, and high gain antennas will be desired to compensate for the propagation ...
Design of wideband omnidirectional dual-reflector antennas in millimeter waves
(2019-05-01)
The work investigates the electromagnetic performance of omnidirectional dual-reflector antennas designed to operate with a frequency bandwidth larger than 45% (25-40 GHz). We consider two antenna configurations, distinguished ...
Design and implementation of a mechanical system for a ground based synthetic aperture radar with automatic antenna pointing: Preliminary results
(Institute of Electrical and Electronics Engineers, 2018-01)
Melting of the snow covering the Andes mountains is a negative result of climate change. It affects the ecosystem that surrounds the snow peaks causing the loss of water resources the human life. Motivated by this situation, ...
