A Design of a Large-Sized Feeding Circuit in C-Band

    Graphical Abstract
    • Abstract
  • In this paper a C-band feeding circuit with 5% relative bandwidth is realized. Firstly the 3D electromagnetic simulation software HFSS and DESIGNER are used to give an initial simulation of the feeding circuit. Then it is realized in a hardware system. Testing results show that the Voltage Standing Wave Ratio(VSWR) is below 1.30 and the phase error is less than 9°. This network has been successfully applied in feeding a line array.
