Problems solved by technology

[0004] The purpose of the present invention is to provide a MIMO antenna for a six-band smart phone, which mainly solves the problem in the prior art that it is not suitable to install multiple antennas in a mobile phone due to the fact that the antenna covers too few frequency bands and the size is too large. Too much coupling between multiple antennas will not be able to meet the given performance indicators and people's needs

Embodiment

[0029] In order to solve the problem existing in the prior art that the frequency bands covered by the antenna are too small and the size is too large, it is not suitable to install multiple antennas in the mobile phone, and too much coupling between multiple antennas will make multiple antennas unable to meet the given performance indicators, problems that do not meet people's needs, such as figure 1 As shown, the present invention discloses a six-band smartphone MIMO antenna, which mainly includes: a printed board 100, a first antenna 001, a second antenna 002 (there may be multiple antennas according to coverage requirements) and an "inverted L-shaped" Metal sheet 003, wherein, one surface of the printed board 100 is printed with a printed board metal ground 90, as a preference, the printed board metal ground 90 includes a main metal ground and an extended metal ground, and the other surface of the printed board 100 is blank. The metal copper-clad substrate, the first anten...

Abstract

The invention discloses a six frequency band smart phone MIMO (Multiple Input Multiple Output) antenna, and mainly solves the problems that in the prior art, a plurality of antennas are not suitable for being mounted in a mobile phone, and the antennas are enabled not to meet the given performance index due to coupling of the antennas, so that people' requirements cannot be met. The six frequency band smart phone MIMO antenna comprises a printing plate, a printing plate metal ground arranged on one surface of the printing plate, and a blank metal-free copper-coated substrate arranged on another surface of the printing plate; more than two antenna routings are arranged on the blank metal-free copper-coated substrate, and each antenna routing comprises the structure that a gap is formed between every two adjacent coupled feeding units; the direct feeding unit is connected with a micro-strip feeder; an 'inverted L-shaped' sheet metal is arranged between every two antenna routings which are symmetrical relative to the 'inverted L-shape' sheet metal. Through the scheme, the antenna achieves the purpose of conformance to requirements, and has high practical promotional values.

Description

technical field [0001] The invention relates to a terminal antenna, in particular to a MIMO antenna for a six-band smart phone. Background technique [0002] The antenna is a component used to effectively transmit or receive electromagnetic waves in a radio system. Its main function is to complete the conversion between electromagnetic waves and guided waves in the receiving system or perform the opposite transformation in the transmitting system. In recent years, with the rapid development of mobile communication services and the high integration of integrated circuits, especially the emergence of communication-specific chips, the communication system is gradually developing towards miniaturization. In contrast, the antenna, which is one of the essential components of wireless communication, is difficult to make smaller. In addition, the traditional wireless communication system uses a transmitting antenna and a receiving antenna, called single input single output (SISO) s...
