A conventional ground station can establish a single downlink with only one satellite at a time through steerable high-gain antenna. In addition to the lack of tracking more than one satellite at once, such single radio communication is highly vulnerable to outages&#x...

This paper presents the design and analysis of a traditional printed log-periodic dipole array antenna with two feeding methods: direct feeding and straight coaxial feeding. Ten linear dipoles have been arranged in logarithmic style to cover an operating frequency bandwidth...

Hybrid pixel detectors of Timepix3 technology allow noiseless single particle detection and identification. We exploit this capability for a comprehensive study of ionizing energy losses and their spatial distribution in silicon sensors after exposure to charged particles and neutrons
