Problems solved by technology

However, all-metal casing communication equipment will bring great difficulties to the antenna design. Usually, in order to ensure the transmission of communication signals, we need to slit the metal casing and replace it with non-metallic materials to cover the antenna area.
However, this design method not only affects the structural strength of the communication equipment, but also increases the difficulty of the production process and also affects the appearance of the entire communication equipment

Embodiment 1

[0021] Such as Figure 1~2 As shown, a MIMO antenna with an all-metal casing includes a circuit board 1, a metal patch 2, a metal casing 3, and a short-circuit nail group 4. The metal patch 2 is printed and covered on the circuit board 1; The nail set 4 is nailed to the circuit board 1 and the metal shell 3 to electrically connect the metal patch 2 and the metal shell 3.

[0022] In the specific implementation process, the MIMO antenna also includes two coaxial feed connectors, namely the first coaxial feed connector 5 and the second coaxial feed connector 6; the coaxial feed connector includes a feeder The electric terminal and the ground terminal are electrically connected with the metal patch, and the ground terminal is electrically connected with the metal shell. Or, the feeding terminal is electrically connected to the metal shell, and the ground terminal is electrically connected to the metal patch.

[0023] In the specific implementation process, the circuit board 1 and th...

Abstract

The invention discloses an MIMO antenna with an all-metal shell, which comprises a circuit board, a metal patch, a metal shell and short-circuit nail groups, and is characterized in that the metal patch covers the circuit board in a printed manner; and the short circuit nail groups are nailed on the circuit board and the metal shell and enable the metal patch and the metal shell to be electrically connected. According to the invention, the antenna is designed by adopting an all-metal conductor, the parts are electrically connected through the metal conductor, and thus a metal shell of communication equipment also becomes a part of the antenna, so that the band coverage of the antenna is increased, and the design of the antenna is successfully completed. The antenna disclosed by the invention is simple in structure, stable in performance and capable of greatly improving the design efficiency.

Description

Technical field [0001] The present invention relates to the field of antennas, and more specifically, to a MIMO antenna with an all-metal housing. Background technique [0002] With the rapid development of mobile communication technology, consumers have higher and higher requirements for the quality and appearance of communication devices (such as mobile phones). At present, most of the existing communication devices use metal shells. Metal shells rely on their beautiful The appearance, solid structure and metal quality have been favored by consumers. However, all-metal shell communication equipment will bring great difficulties to antenna design. Generally, in order to ensure the transmission of communication signals, we need to cut the metal shell and cover the antenna area with non-metallic materials. However, this design method not only affects the structural strength of the communication device, but also increases the difficulty of the production process and also affects t...
