Problems solved by technology

[0004] As a key component of a broadband wireless electronic communication system, the performance of the broadband antenna directly determines the performance of the entire broadband wireless electronic communication system. However, the frequency bands of commonly used broadband antennas are relatively narrow, so it is particularly important to design a broadband antenna with excellent performance. important

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings. What is done is to explain the technical solution rather than limit it. Position qualifiers such as "right" are only relative positions adopted for the convenience of description, and cannot be understood as limitations on the technical solution:

[0032] In order to solve the problem that the working frequency band of the wireless mobile terminal antenna is too narrow and increase the working bandwidth of the antenna, the planar structure antenna in the present invention adopts the arc-shaped slot coupling feeding technology, and reduces the size of the ground plate on the back of the antenna, increasing the radiation range of the antenna .

[0033] Such as figure 1 , figure 2 , image 3 Shown is the broadband monopole antenna with arc-shaped coupling feed structure of the present invention, comprises dielectric substrate 1, and the material of dielectric ...

Abstract

The invention discloses a broadband monopole antenna with an arc-shaped coupling feed structure and belongs to the technical field of wireless communication. The broadband monopole antenna comprises adielectric plate; a metal grounding plate is attached to one surface of the dielectric substrate, and the other surface is provided with a circular radiation patch and a T-shaped feed structure; theT-shaped feed structure is composed of an energy coupling arm and a rectangular arm, wherein the energy coupling arm is arc-shaped, the radian of the energy coupling arm is the same as that of the circular radiation patch, and a gap exists between the energy coupling arm and the circular radiation patch; and the rectangular arm and the metal grounding plate form a micro-strip line structure. The coupling feed structure is adopted, so that the bandwidth of the antenna is expanded, and the port reflection coefficient of the antenna in the frequency range of 1.31GHz to 3.27GHz is smaller than -10dB; and the broadband monopole antenna is simple in structure, reasonable in design, convenient to manufacture and process, and capable of realizing batch production.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a broadband monopole antenna with an arc-shaped coupling feeding structure. Background technique [0002] Wireless communication technology has developed rapidly in recent years, and has developed from the initial analog wireless communication to the current 5G wireless communication. Moreover, people's dependence on wireless communication is getting stronger and stronger, and people's production and life can no longer be separated from wireless communication. As an important component of wireless electronic communication equipment, the antenna is responsible for the reception and transmission of radio waves, and realizes the mutual conversion between high-frequency current and electromagnetic waves. People have higher and higher requirements on wireless communication devices, especially antennas in mobile wireless communication devices also need to be...
