Description

Antenna structure and mobile terminal

Technical field

The present application relates to the field of communications technologies, and in particular, to an antenna structure and a mobile terminal.

Background technique

As the user demands higher and higher communication quality and communication rate, the antenna technology continues to develop. In theory, the more antenna pairs, the higher the transmission rate and the higher the reliability. As users' requirements for transmission rates continue to increase, 4×4 Multiple-Input Multiple-Output (MIMO) will become popular.

Conventional multiple antennas are used to increase the degree of diversity to overcome channel fading. Signals with the same information are transmitted through different paths, and multiple independent fading replicas of the data symbols can be obtained at the receiver end, thereby achieving higher reception reliability.

The MIMO system is a core technology used in 802.11n. It uses multiple antennas to suppress channel fading. MIMO technology can be roughly divided into two categories: transmit/receive diversity and spatial multiplexing. The advantage of MIMO is the ability to increase the wireless range and improve performance. 4×4 MIMO refers to a MIMO system employing four inputs and four output antennas. Compared with the traditional MIMO system including 1 × 2, 2 × 3 and 3 × 3 MIMO, 4 × 4 MIMO can support up to 4 data streams at the same time, so that its throughput is 4 times that of a single-input single-output system of the same bandwidth. There is no doubt that devices equipped with 4×4 MIMO technology will have faster network speeds. This technology is currently used on some high-end laptops, but the phone is not used.

At the same time, with the advancement of materials and industrial design, people have more new demands on the design of mobile terminals, and the representative ones are the emergence and popularity of mobile terminals with metal casings (including metal backplanes).
