Antenna and wireless communication device

Abstract

The embodiment of the invention provides an antenna and a wireless communication device. The antenna is connected with a conductive substrate, and comprises a first radiator, a feed point and a second first radiator, wherein the first radiator is formed as a closed metal ring; one end of the feed point is connected with the first radiator, and the other end of the feed point is connected with the conductive substrate; the second radiator is formed as the metal ring which is closed or has an opening; the second radiator is adjacent to the first radiator according to a preset distance; and a gap is reserved between the first radiator and the second radiator. The antenna has ultra-wide bandwidth, and the working frequency band of the antenna is from 824MHz to 2484MHz and covers GSM850, GSM900, DCS, PCS, UMTS2100, GPS, Bluetooth and other frequency bands commonly used by the conventional wireless communication device. Therefore, the ultra-broadband of the antenna is realized so as to allow the wireless communication device to support more frequency bands.

Description

Technical field [0001] The present invention relates to antenna technology of communication devices, and in particular to an antenna and a wireless communication device having such an antenna. Background technique [0002] With the development of wireless communication technology and the increasing popularity of mobile communication, the performance requirements for terminal communication devices such as mobile phones are also getting higher and higher. The same terminal communication equipment needs to support multiple different frequency bands to meet the needs of people roaming between different countries and regions and switching between 2G and 3G networks. This has led to an increasing demand for antennas with multi-band and broadband characteristics. [0003] At the same time, considering the difference between the performance of terminal equipment in free space and actual use by users, more and more attention has been paid to the wireless performance of terminal equipment i...

AI Technical Summary

Problems solved by technology

Due to the narrow bandwidth of the antenna, it is impossible to solve the problem that the performance of the antenna is deteriorated by the head model and the hand model, that is, because the bandwidth of the antenna is limited, the performance of the head and hand model is often difficult to meet the index requirements;

[0009] Secondly, the space requirements of the antenna are relatively large, and there is rarely enough space in the terminal products that require miniaturization;

[0010] Finally, the antenna cannot meet the requirements of other frequency bands, such as the requirements of GPS and Bluetooth frequency bands
