Dual-polarized full-wave oscillator based on radiating surface defect coupling

Abstract

The invention discloses a dual-polarized full-wave oscillator based on radiating surface defect coupling. The dual-polarized full-wave oscillator comprises a metal radiating surface arranged on a dielectric plate, a supporting conductor feeding the metal radiating surface and a reflective grounding plate, wherein one end of the supporting conductor is connected with the reflective grounding plate,and the other end of the supporting conductor is connected with the metal radiating surface; the metal radiating surface is horizontally arranged above the reflective grounding plate; the metal radiating surface is formed by four equivalent conductor rings arranged symmetrically in a cross shape; and the central position of the outer edge of each conductor ring breaks radiating arms at the two sides of a central gap, wherein a resistor structure equivalent to a zero impedance value is connected to the braking position, and the resistor structure equivalent to the zero impedance value is connected with the radiating arms at the two sides in a defect coupling mode. By loading a zero-resistance defect coupling mechanism to the middle of each conductor ring of the metal radiating surface of the oscillator, current paths are more diversified, excessive centralization of currents is avoided, resonance is effectively avoided, and therefore a directional diagram is perfected.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-polarized full-wave oscillator based on defect coupling of a radiating surface. Background technique [0002] The radiation surface structure of the current PCB full-wave oscillator is as follows: figure 1 As shown, it is directly connected by four folded structures, and its radiating arm is longer, resulting in a too long current path, which induces high-order resonance and causes serious deformation of the pattern; and the distance between the two polarization feed points on the floor is relatively close, resulting in polarization poor isolation. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a dual-polarized full-wave vibrator based on defect coupling of the radiating surface, and a zero-resistance defect coupling mechanism is loaded in the middle of each conductor ring on the metal radiati...
