Abstract: In this article, a wideband circularly polarized helical antenna array featuring high radiation efficiency is proposed. To achieve a broadband circularly polarized (CP) performance, the two ...

An ultra-compact, low-power 150 GHz radio module enabling high data rates in mobile devices has been developed by researchers ...

The core portion of NASA's Nancy Grace Roman Space Telescope has successfully completed vibration testing, ensuring it will ...

European astronomers have investigated a galaxy cluster designated CIZA J2242.8+5301, dubbed the Sausage cluster. The ...

Introduction Radio interferometry is a technique in radio astronomy where signals from two or more radio telescopes are ...

It comprises an array of 42 antennas, each 6 meters in diameter, which can be simultaneously used for both SETI and cutting-edge radio astronomy research. The ATA is currently being upgraded with more ...

each port of the antenna system excites the entire aperture of the antenna array, leading to the improved gain while maintaining the half-power beamwidth (HPBW) at around 70 degrees. Besides, the ...
