The present invention proposes a novel 1700-3800MHz ultra-broadband dual-polarized oscillator, which is characterized in that it includes a reflector, an electromagnetic wave radiation oscillator and a support portion, the electromagnetic wave radiation oscillator is fixed on the top of the support portion, and the bottom surface of the support portion is fixed on the reflector plate; The vibrator includes a substrate, and both sides of the substrate are covered with copper foil to form a double-sided printed circuit; the front side of the electromagnetic wave radiation vibrator includes two mutually orthogonal half-wave vibrators, four excitation vibrators and two polarization isolators, each half-wave vibrator. Each end is provided with a mutually coupled excitation oscillator, and the two polarization isolators are symmetrically arranged between the positive and negative half-wave oscillators; The invention expands the coverage frequency range and realizes the effect of widening the frequency; and the volume is small, which reduces the occupied space; the overall optimized structure design makes it high radiation efficiency, strong anti-interference, and has strong practicability. |
