Embodiment Construction
[0023] refer to figure 1 , figure 2 , image 3 , a multi-port frequency-division electronically adjustable antenna, including a reflector 1 and a feed network module, the feed network module includes a phase shifter module 2, a frequency divider array 3 connected to the phase shifter module 2, and The power divider 4 connected to the phase shifter module 2, the back of the reflector 1 is connected to the frequency divider array 3, and the front of the reflector 1 is installed with a broadband dipole composed of a dipole unit 5 in a non-conductive manner Sub-array 6, wherein the center frequency wavelength of the dipole unit 5 is λ, wherein the power divider 4 distributes power for the dipole unit 5, and the phase shifter module 2 can distribute the phase for the dipole unit 5, specifically by Composed of several slow-wave phase shifters, the appearance of slow-wave phase shifters is a fan-shaped structure, which can be superimposed into two groups. The two groups of phase s...
