Aiming at the application requirements of satellite navigation antennas in extreme environments, a miniaturized, high-temperature-resistant and anti-interference satellite navigation antenna design scheme integrating composite materials and ceramic microstrip antennas are proposed. The antenna is endowed with excellent heat insulation and wave transmission performance by introducing quartz fiber reinforced silica composite materials. Ceramic microstrip antenna units that are small in size, light in weight and resistant to high temperatures are adopted to meet the signal reception requirements under high-temperature conditions. The experimental results show that the design meets high temperature application.
