Directional antenna, directional antenna device and wireless coverage system

Abstract

The present invention provides a directional antenna, comprising: a first substrate, the first substrate has a first surface and a second surface; at least one first dipole antenna unit, the first dipole antenna unit is arranged on The first surface, the first dipole antenna unit includes two first dipole units; the metal surface, the metal surface is covered on the second surface, one of the first dipole units One end is electrically connected to the metal surface; and a power feeding part is electrically connected to one end of another first dipole unit. The directional antenna of the present invention has the characteristics of good directivity and good electromagnetic signal processing ability, and at the same time has high gain, wide frequency bandwidth, and small standing wave ratio, which enhances the ability to receive and send electromagnetic signals, and can well complete data in wireless coverage systems Interaction improves user experience and can meet the needs of existing wireless coverage systems for wireless signal processing capabilities.

Description

technical field [0001] The invention belongs to the field of communication equipment, and in particular relates to a directional antenna, a directional antenna device and a wireless coverage system. Background technique [0002] With the development of wireless communication technology, more and more mobile communication terminals are put into use, such as mobile phones, PADs, etc., and the data processing capabilities of these mobile terminals have increased significantly. The ability to provide data puts forward higher requirements. [0003] In public places such as museums and exhibition halls, a large number of mobile terminals will be used at the same time to upload videos, pictures, or release messages. There will be a large amount of data transmission demand in a short period of time, which will easily cause network data congestion. As the radiating unit and receiving device of the final radio frequency signal, the directional antenna's working characteristics will d...

AI Technical Summary

Problems solved by technology

[0004] Existing directional antennas are mostly made of a combination of vibrators and composite material substrates, and there are problems such as high thickness of the vibrator and large loss of composite material substrates, so that the wireless coverage system using the directional antenna has problems such as low data processing efficiency and limited processing speed. , so there is an urgent need for a directional antenna with good directivity and high throughput to solve the problem of insufficient data capacity in wireless coverage systems
