"A wideband metal-only patch antenna for cubesat" by Suhila Abulgasem, Faisel Tubbal et al.

This article presents a compact wideband high gain patch antenna for CubeSat. The proposed metal-only antenna mainly consists of an upper patch, a folded ramp-shaped patch and shoring pins connecting the antenna with the ground plane. By adjusting the lengths and widths of two arms of the upper F-shaped patch, a second resonant frequency is generated, and hence, the −10 dB bandwidth is increased. Moreover, the effect of arms’ lengths and widths on reflection coefficients, operating frequency and bandwidth is presented. To validate the design and the simulation results, a prototype metal-only patch antenna was fabricated and tested in a Chamber. A good agreement between the simulated and measured results is achieved. The measured results show that the fabricated prototype achieves a −10 dB bandwidth of 44.9% (1.6–2.7 GHz), a small reflection coefficient of −24.4 dB and a high efficiency, i.e., 85% at 2.45 GHz. The radiation performance of the proposed antenna is measured, show ....

5G wireless energy can be harvested to power IoT devices
Shares
Scientists from Georgia Tech have found a way to reliably harvest the energy from 5G at 28Ghz, overcoming antenna problems that previously required such solutions to be within line of sight of a tower.
The wireless power grid that can power your car, phone, connected appliances and more is still the stuff of science fiction, and despite advances from Ossia, Energous, Xiaomi and Motorola, there s still no wireless power systems available to power your devices in the same way that Wi-Fi delivers the Internet to your smartphone, tablet, computer and other technologies. ....
