Since satellites are always in different locations, it can be challenging to repeat a test environment for CRPA testing. Historically, testing Controlled Reception Pattern Antenna (CRPA) systems in a ...

Antenna design is often referred to as a black art or witchcraft, even by those experienced in the space. To that end, [Janne] wondered—could years of honed skill be replaced by bruteforcing the ...

Abstract: A 1×2 antenna array with three-parameter independently controllable reconfiguration of polarization, frequency and radiation pattern is proposed. One C-shaped slot and two PIN diodes are ...

Abstract: This paper presents a quad-port pattern-diversity cross-shaped dielectric resonator (DR) antenna (DRA). The DRA is fed by four feeding strips connected to the outputs of two printed 180° ...

Understanding Earth's radiation balance requires capturing outgoing radiation across the entire planet. Traditional satellite platforms face limitations: low-Earth-orbit satellites provide detailed ...
