Problems solved by technology

However, when this kind of antenna is to be used as a multi-frequency antenna, its planar radiation part needs to occupy a large plane area, and the distance d0 between the radiation plane and the substrate plane (Figure 1) is related to the frequency / bandwidth of the antenna, so can not be adjusted arbitrarily
Therefore, the volume occupied by the existing antenna architecture cannot be effectively reduced, and it is difficult to meet the requirements of miniaturization and multi-frequency

Embodiment Construction

[0031] Please refer to FIG. 2 , which schematically shows an embodiment of an antenna 20 of the present invention in views from different angles. The antenna 20 of the present invention can be a monopole antenna, which is provided with a connection part CP, a low-frequency radiation part L and a high-frequency radiation part H, so that the antenna 20 of the present invention can function as a multi-frequency antenna and support wireless communications in various frequency bands need. As shown in Figure 2, the antenna 20 of the present invention can be formed by twisting a conductor with a uniform cross section (for example, a metal copper wire with a circular cross section), and its low frequency radiation part L and high frequency radiation part H are different from the connecting part CP respectively. The (opposite) two ends start to extend and form a three-dimensional wrapping structure. The connection part CP can accept the feed-in / feed-out of electronic signals through i...

Abstract

The disclosed miniaturized multi-frequency antenna comprises: a uniform-section conductor connection part for signal I / O, a LF first radiation part on one side of the connection part for forming three main segments along two planes, and a HF second radiation part forming two segments on one plane, wherein the ends of two radiation parts are paralleled for coupling performance. This invention reduces size and improves entire performance.

Description

technical field [0001] The present invention relates to a miniaturized multi-frequency antenna, in particular to a miniaturized multi-frequency monopole (monopole) which has a three-dimensional winding structure and can effectively utilize the mutual coupling characteristics between radiating parts of different frequency bands to improve antenna characteristics antenna. Background technique [0002] In the modern information society, various wireless communication networks have become one of the most important ways for the public to exchange voice or text information, data, materials, and audio-visual files. Access to these wireless communication networks that carry information through wireless electromagnetic waves requires the use of antennas. Therefore, the research and development of antennas has become one of the key points of modern information manufacturers. In order to allow users to integrate and access multiple different wireless communication networks more conven...
