Embodiment 1

[0032] Please refer to figure 1 , figure 2 , image 3 , Embodiment 1 of the present application provides an antenna mechanism, including:

[0033] Antenna substrate 101;

[0034] Four first antennas 102, the first antennas are rectangular, and two by two are arranged on the first surface of the antenna substrate orthogonal to each other; the first antennas are monopole antennas, and the monopoles An L-shaped slot 104 is provided on the antenna. During actual operation, the orientations of the L-shaped slots 104 on the four monopole antennas are consistent, so that the electromagnetic wave field of the antenna mechanism can be evenly distributed in space, further ensuring the circular polarization characteristics of the antenna mechanism. Still further, the relative bandwidth of the monopole antenna may belong to the bandwidth range of 10% to 20%, thereby ensuring that the antenna mechanism has high-quality broadband communication performance. As a preference, the relativ...

Abstract

The invention discloses an antenna mechanism. Four first rectangular antennas, each two of which are mutually orthogonal to each other, are arranged on an antenna substrate. A phase-shifted feed network is arranged on the antenna substrate and is used for feeding power to the four monopole antennas, wherein the feeding phases are orthogonal to each other. According to the invention, with the fourfirst rectangular antennas arranged orthogonally, the circular polarization of the antenna is realized based on a feeding mode with the orthogonal feeding phases; and on the basis of the setting modeof all parts of the antenna mechanism, technical effects of miniaturization and high gain of the antenna mechanism are guaranteed.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an antenna mechanism. Background technique [0002] The circular polarization of the antenna means that the electromagnetic wave field of the antenna is synthesized by two mutually orthogonal linearly polarized waves. When the two orthogonally polarized waves have equal amplitudes and a phase difference of 90 degrees, a circularly polarized antenna is formed. When the antenna achieves circular polarization performance, no matter what the polarization direction of the receiving antenna is, the induced signal will be the same, and there will be no difference. Therefore, the antenna with circular polarization performance can reduce the sensitivity of the system to the orientation of the antenna, and is especially suitable for installation on devices that need to be in a moving state. [0003] At present, in order to achieve miniaturization, traditional antennas usual...
