A Multi-band and Multi-functional Conformal Array Antenna

According to the requirements of electronic information system and platform for multi-functional integration of radar, communication and navigation, the methods and technologies to expand the working bandwidth of antenna are studied. An ultra-wideband conformal element and array antenna with operating frequencies across Band P, L, S, C and X are designed and realized by comprehensively using coplanar waveguide feeding, loading matching branches, edge deformation of radiation structure, metamaterial loading and microwave holographic control. The measured data are in good agreement with the simulation results, which provides a potential antenna for multi mission integrated electromagnetic radiation and reception.
