Heat-resistant microstrip antenna array for hypersonic aircraft with small radar visibility

Technical implementation of the microstrip antenna array of segmented design has been proposed. It is shown that at the expense of using heat-resistant materials the antenna array has stable parameters of radiation at high temperatures and can be used for radio engineering systems of hypersonic aircraft. The investigation results were also presented demonstrating a significant reduction of the scattering cross-section of such antenna as compared with the equivalent planar antenna array.
