Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] figure 1 It is a schematic structural diagram of a dual-band antenna in an embodiment, and the dual-band antenna includes a dielectric plate 100, a feeder 200, a first dipole antenna, and a second dipole antenna. The first dipole antenna serves as the radiation oscillator of the first frequency band, and the second dipole antenna serves as the radiation oscillator of the second frequency band. Wherein, the first frequency band and the second frequency band have different frequency ranges, so that one of them is relatively low frequency band and the other is relatively high frequency band. ...

Abstract

Disclosed is a dual-band antenna. The dual-band antenna comprises a dielectric plate, a feed end, a first dipole antenna and a second dipole antenna, wherein the feed end is arranged on the dielectric plate; the first dipole antenna is arranged on the dielectric plate; the first dipole antenna comprises a first radiation part and a first grounding part; the first radiation part and the first grounding part both extend to opposite directions by taking the feed end as the starting point; the first dipole antenna is used as a radiation vibrator of a first frequency band; the second dipole antenna is arranged on the dielectric plate; the second dipole antenna comprises a second radiation part and a second grounding part; the second radiation part and the second grounding part both extend to opposite directions by taking the feed end as the starting point; the extension direction of the second radiation part is perpendicular to that of the first radiation part; and the second dipole antenna is used as a radiation vibrator of a second frequency band, wherein the first dipole antenna and the second dipole antenna form plus or minus 45-degree crossed and polarized dual-band antennas. According to the dual-band antenna, the stability of the antenna is effectively improved. The invention also provides wireless communication equipment.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless communication device and a dual-frequency antenna thereof. Background technique [0002] In recent years, wireless network technology has developed rapidly by leaps and bounds. The devices supporting wireless connection are increasing rapidly. The density of requirements is increasing, resulting in an increasing number of antennas used in wireless communication devices. Limited by the internal space of the device, the number of antennas that can be placed inside is limited. In order to save space and increase the number of antennas, more and more antennas are designed as dual-frequency antennas. Based on the design method of the traditional dual-frequency antenna, the two frequency bands have a greater influence on each other, which makes the performance stability of the antenna poor, and the consistency of the test antenna parameter indicators is not ...
