Electrically adjustable independent multi-frequency and multi-beam antenna

Abstract

The present invention relates to an electrically adjustable, multi-frequency, multi-beam, stand-alone antenna comprising: a first electromagnetic lens, a second electromagnetic lens, a mounting plate, a reflector plate, oscillator units A1 to A32, oscillator units B1 to B8, and phase shifters C1 to C12. The first and second electromagnetic lenses are both cylindrical lenses. Oscillator units A1 to A32 operate at a higher frequency than oscillator units B1 to B8. The first electromagnetic lens, the second electromagnetic lens, the reflector plate, and the mounting plate are fixed together. Oscillator units A1 to A32 and oscillator units B1 to B8 are all mounted on a reflective surface of the reflector plate. Phase shifters C1 to C12 are all mounted on the mounting plate.Each set of four high-frequency oscillators and each set of two low-frequency oscillators are connected to a phase shifter. The present invention is characterized by a simple structure, scientific design, small size, flexible beam direction configuration, etc.
