Embodiment Construction
[0032] The following is attached Figure 1-3 The application is described in further detail.
[0033] The embodiment of the present application discloses an antenna built into a wireless network terminal device.
[0034] refer to figure 1 The antenna includes an antenna radiator 1 and a signal chip. The antenna radiator 1 is made of metal parts. In this embodiment, the metal parts include silver, copper and aluminum, and the signal chip is connected to the antenna radiator 1 .
[0035] In the use of antennas, directivity (referring to the out-of-roundness of the antenna's horizontal plane) is one of the important performance indicators of the antenna. For example, antennas with good directivity are relatively strong in the horizontal plane of 360 degrees, while antennas with poor directivity In the horizontal range of 360 degrees, it is relatively strong in a certain direction, but relatively weak in other directions; the antenna radiator 1 processed with a metal structure h...

The invention discloses an antenna built in wireless network terminal equipment, and belongs to the field of antennas. The antenna comprises an antenna radiator made of a metal piece and a signal chip connected with the antenna radiator. The routing shape of the antenna radiator comprises a bent shape or a concentric-square-shaped shape; the concentric-square-shaped shape comprises a square-shaped feed line and a C-shaped feed line, the square-shaped feed line is defined by feed lines connecting the grounding point and the feed point, and the C-shaped feed line is connected with one end of the square-shaped feed line, surrounds the square-shaped feed line and is close to the grounding point; a gap is formed between the feeder lines connecting the grounding point and the feeding point, and a gap is formed between the square feeder line and the C-shaped feeder line; the bandwidth of the antenna is adjusted by adjusting the width of the feeder line or the size of the gap of the antenna radiator. The application has the effect of facilitating bandwidth expansion.
Description
technical field [0001] The invention relates to the field of antennas, in particular to an antenna built into a wireless network terminal device. Background technique [0002] With the development of wireless network technology, wireless network terminal equipment such as cameras, projectors, and remote controls are becoming more and more miniaturized, which gradually reduces the available space inside the terminal equipment, and the requirements for the appearance of the antenna need to be more precise. , compact. [0003] At present, the antenna of the mobile terminal usually adopts a ceramic antenna or an antenna sintered with metal and ceramic, which is relatively large in size. [0004] Regarding the above-mentioned related technologies, the inventor believes that there are defects in that: the traditional antenna is difficult to debug due to its large size, it is not convenient to expand the bandwidth, and it is difficult to meet the application of wireless network te...
