Chinese engineers have developed a new ultra-thin and compact antenna designed to improve communication and navigation for next-generation fighter jets while enhancing aircraft stealth by reducing radar detectability.
The innovation was detailed by the “South China Morning Post” and involves an antenna model that, at just 0.047 times the wavelength of low-frequency signals, has been adapted to the increasingly flat profile of fighter jets.
The antenna features eight elements arranged in a circular array, allowing it to integrate seamlessly into the aircraft’s structure without affecting its aerodynamic performance or the frequency bands in which it operates. Additionally, the new antenna enhances the fighter jet’s stealth by minimizing its heat signature and making radar detection more difficult.
This technology provides China with a strategic advantage, especially amid rising political tensions with the United States, as both nations invest heavily in advanced military technologies.
The new antenna version overcomes the limitations of the previous model, which was larger and operated only within a narrow frequency range. By reorganizing the antenna elements into a circular array, engineers managed to expand its operating range without increasing its size, while preserving the aircraft’s stealth capabilities.
The antenna is also omnidirectional, optimizing communication, and features a short-circuit wall that improves electrical efficiency and makes radar detection more challenging.
