UF engineers, backed by DARPA and NASA, are perfecting laser-forming techniques that let metal sheets fold themselves into ...
Abstract This article explores the performance of a Yagi-Uda patch antenna with Koch fractal geometry of different orders on an FR-4 substrate. It exhibits multiband operation, enabling the use across ...
Construction of the new antenna has been underway for more than four years, and during the installation, teams used a crawler crane to lower the 133-ton metal skeleton of the 112-foot-wide ...
This work proposes a phase-only synthesis technique for shaping the beam of a circularly polarized dual-reflector antenna with a subreflector consisting of a reflectarray and a main parabolic ...
Parabolic space heaters are a type of infrared heater that use a parabolic reflector to aim the heat in a concentrated beam. Here’s why you should try one. How infrared heat works ...
A parabolic antenna is a simple enough device, a curved reflector designed to focus all the radiation from the direction it’s pointed into a waveguide or antenna at its feedpoint. They’re easy ...
The parabolic surface of the antenna in Figure 1 is described by: ρ′2 = 4F(F −zf), p′ ≪ a ρ ′ 2 = 4 F (F − z f), p ′ ≪ a (1) Here, ρ′ ρ ′ is the distance from a point A to the focal point O, where A ...

If Viasat declares it a total loss, the ViaSat-3 Americas satellite is insured for $420 million. That would be the largest known insurance claim for the loss of a satellite. But a person familiar ...
Each satellite's reflector is designed to deploy atop a long boom. In a pre-launch interview, David Ryan, president of space and commercial networks for Viasat, said the size of the mesh antenna ...
