Abstract

The invention discloses an antenna device. The antenna device is used for a handheld mobile terminal, wherein the handheld mobile terminal comprises a shell; a LOGO identification area is arranged onthe shell; the antenna device is connected with the shell of the LOGO identification area; and the shell of the LOGO identification area serves as a radiator of the antenna device for receiving and transmitting a wireless radio frequency signal. According to the antenna device, the LOGO of the handheld mobile terminal shell can be used as the radiator of the antenna, so that the number of antennasis increased without changing the ID of the whole machine, and the MIMO technology of the multiple antennas is applied.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to an antenna device. Background technique [0002] Miniaturization, multiple frequency bands and MIMO (Multiple Input Multiple Output) multiple antenna technologies have become the development direction of handheld communication terminal antennas. For the MIMO system to take advantage of its advantages, it must use multi-antenna MIMO technology at the transmitter and receiver at the same time. However, due to the limitation of the geometric size of the mobile terminal and the thinner and thinner its thickness, various devices are becoming more and more concentrated, and the space available for antenna layout is getting smaller and smaller, making the use of multi-antenna MIMO technology in mobile terminals It becomes very difficult. Summary of the invention [0003] The antenna device provided by the present invention can use the LOGO of the shell of the han...
