Abstract

The invention discloses a high-gain circularly-polarized antenna. The high-gain circularly-polarized antenna comprises a metal box body, a first dielectric substrate and a second dielectric substratewhich are sequentially stacked from bottom to top, wherein a parasitic patch is arranged on the upper surface of the second dielectric substrate, a radiation patch is arranged on the upper surface ofthe first dielectric substrate, and the parasitic patch and the radiation patch are arranged face to face; the third dielectric substrate is arranged in the metal box body, and a Wilson power divideris arranged on the third dielectric substrate; an SMA coaxial connector is arranged on the side wall of the metal box body; a shunt port of the Wilson power divider is electrically connected with theradiation patch, and a combination port of the Wilson power divider is connected with the SMA coaxial connector to feed external equipment, so circularly-polarized wave radiation is realized; and theradiation patch is provided with a U-shaped gap. The high-gain circularly-polarized antenna provided by the invention has the characteristics of simple structure, high gain, small size and the like.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a high-gain circularly polarized antenna. Background technique [0002] Antenna is an important component module in the maritime satellite communication system, and its performance can directly affect the performance of the entire maritime satellite communication system. At present, the antennas of maritime satellite communication systems are generally realized by circularly polarized antennas. The circularly polarized antennas are used to receive signals. On the one hand, it can reduce signal loss, and on the other hand, it can eliminate the polarization distortion caused by the Faraday rotation effect of the ionosphere. [0003] However, the antennas in the existing maritime satellite communication system have problems such as low gain and large volume, which greatly affect the system performance of the maritime satellite communication system.
