| Abstract: | In this paper,a new duplex feed with five cross-dipole antennas is presented.Its tracking frequency range extends to 300MHz.The VSWR is less than 1.6 in the operating frequency range.The zero depth of the deference beam is deeper than 30dB,and the cross coupling is less than 25%.The design methods of the antenna array and feed net are introduced.And the test results are given. |
