China shrinks jet antenna to 0.047 times wavelength to boost fighter’s stealth power
Published on March 3, 2025
The evolution of military aircraft design has increasingly emphasized stealth and aerodynamic efficiency, pushing engineers to develop low-profile antennas that integrate seamlessly with an aircraft’s structure. Traditional antennas, with their protruding forms, create unwanted radar signatures and disrupt airflow, posing significant challenges for stealth technology.
However, a breakthrough study from researchers at the Southwest China Institute of Electronic Technology and the University of Electronic Science and Technology of China (UESTC) introduces an innovative ultra-wideband omnidirectional circular ring antenna, which may redefine how communication and navigation systems are embedded into modern aircraft.
