【Abstract】 The overwhelming research on reconnaissance and surveillance radar system in aerospace is highlighted in low profile,light weight,high efficiency,multi-band,multi-polarization,and common aperture waveguide slot phased array antenna.A new concept is proposed in this study to realize the multi-polarization and multi-band common aperture of waveguide slot antenna by embedding or stacking the irregular waveguides.The technical approaches and solutions of realizing common aperture,high efficiency,low profile and light weight of waveguide slot antenna by means of embedding or stacking the irregular waveguides are studied.The three matching problems in the research of waveguide slot antenna are explored.The technology and research means of the three matching problems such as structural mode,radiation antenna aperture field and multiple physical field integration are described,which lays the foundation for the coming research on multi-polarization,multi-band and common aperture waveguide slot phased array antenna.更多还原
