Problems solved by technology

Insufficient signal strength due to the directional divergence of the omnidirectional antenna, and insufficient ability to deal with special scenarios (such as single signal exits such as underground garages and elevator shafts) lead to weak signals of communication products
However, the directional antenna is large in size and difficult to install, and its directivity will not change. It is still insufficient for multi-scenario compatible design.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an antenna device. Background technique [0002] Wireless communication products have entered a period of rapid development, and product terminals will face diversified, multi-scenario, and intelligent design requirements. The built-in antenna design of existing terminal communication products is mainly directional antenna or omnidirectional antenna. Due to the divergence of omnidirectional antenna directionality, the signal strength is insufficient, and the ability to deal with special scenarios (such as single signal exits such as underground garages and elevator shafts) is insufficient, resulting in weak signal of communication products. However, the directional antenna is large in size and difficult to install, and its directivity will not change. It is still insufficient for multi-scenario compatible design. Contents of the invention [0003] The embodiment of ...
