Problems solved by technology

[0003] Traditional microstrip antennas (for example, monopole antennas) can only achieve about 1% of the bandwidth, which belongs to point frequency antennas, so it is difficult to directly apply to mobile communications that require broadband
The mobile phone antenna is another widely used antenna. However, in order to increase the bandwidth, the complexity of the antenna structure not only increases sharply, but also is limited by the overall structure of the mobile phone and the metal environment of the PCB. At the same time, the consistency of the entire frequency band cannot be guaranteed.

Embodiment

[0039] For the convenience of description, the relevant terms used in the specification are firstly explained and defined.

[0040] The "strip shape" (for example, a strip electrode) referred to in this application refers to a shape with a constant width extending along a track. In some embodiments, the trajectory of the "bar" can be composed of one or more straight line segments. In other embodiments, the trajectory of the "bar" can also be composed of one or more curved segments or can be composed of straight line segments and Combination of curve segments. figure 1 Various "bar" shapes are schematically shown in , their widths being marked with "W".

[0041] The "length" of a bar in this application refers to the length of the extended locus of the bar taken from the midpoint of the width. For example, if figure 2 Schematically stated in , the "length" of a bar refers to the total length of the extended trajectory taken along the midpoint of the bar's width, represente...

Abstract

The invention relates to an antenna for communication, which comprises a substrate, a top part antenna layer, a bottom antenna layer; the substrate is provided with a top surface and a bottom surfacein opposite to the top surface; the top part antenna layer is arranged on the top surface and comprises a first strip electrode, a second strip electrode and a third strip electrode which are introduced from the same node on the top surface and outwards dispersed; the bottom antenna layer is arranged on the bottom surface and connected with the top part antenna layer by crossing through a substrate through a coaxial feed point. Compared with a traditional multi-frequency terminal antenna, the antenna has better gain characteristic and realizes broadband property instead of point frequency; theantenna has smaller dimension, the structure is simple and easy to realize.

Description

technical field [0001] The invention relates to the communication field, in particular to an antenna for communication. Background technique [0002] With the popularization of 4G communication (its main communication frequency range is 700MHz-2700MHz), requirements such as broadband, small size, and stable performance have been put forward for antennas used for mobile communications. [0003] Traditional microstrip antennas (for example, monopole antennas) can only achieve about 1% of the bandwidth, which belongs to spot frequency antennas, so it is difficult to be directly applied in mobile communications that require broadband. The mobile phone antenna is another widely used antenna. However, in order to increase the bandwidth, the complexity of the antenna structure not only increases sharply, but also is limited by the overall structure of the mobile phone and the metal environment of the PCB. At the same time, the consistency of the entire frequency band cannot be guar...
