摘要：

This letter presents a high-temperature stable antenna array applied to an adaptive anti-jamming system in satellite navigation. The main features of the antenna are: owing to the titanium alloy and thermal stable ceramic material, the antenna works stably at 400 degrees C and demonstrates excellent heat-resisting property; no welding is used during the assembly to ensure the reliability of the electric connection under high temperature impact; metal walls are adopted to improve the radiation; the center shorting pillar is designed to reduce the inductance of the feed probe and obtain excellent impedance matching characteristics. During the simulation and experiments, the designed antenna array exhibits excellent performance and proves its suitability for high-temperature application. From 20 degrees C to 400 degrees C, the right-hand circular polarization gain is larger than 4 dBi and the operation frequency covers the L1 band of global positioning system and B1 band of BeiDou II.
