GW-Level High-Power Radial Line Helical Array Antenna

  • Received Date: 12 Oct 2007

  • In order to raise the power-handling capacity of a high-power radial line helical array antenna and realize the directional radiation of GW-level high-power microwaves,a GW-level 4-ring 48-element radial line helical array antenna using H-coupled probes was designed based on the improvements of element helical antenna and array arrangement.Theoretical analysis,numerical simulation and experimental measurement of this radial line helical array antenna were carried out.The result of the experimental measurement shows that in the range of 3.6 to 4.1 GHz,the antenna gain is over 22 dB,the antenna axial ratio is below 2 dB,and the aperture efficiency is more than 55%.
