Abstract

The invention discloses an antenna structure and method for enhancing antenna directivity, and a temperature controller. The antenna structure comprises a communication module with an onboard antenna,an auxiliary antenna disposed outside the communication module. The onboard antenna and the auxiliary antenna are connected to a control switch of the communication module. The onboard antenna or theauxiliary antenna is enabled by switching the control switch. The antenna structure can increase the signal coverage of the communication module and enhance the directivity of the onboard antenna.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna structure, a method and a temperature controller for enhancing antenna directivity. Background technique [0002] The WIFI module is a common communication module, which generally uses an on-board antenna, which occupies less space and costs less. Most of the built-in onboard antennas use the antenna effect of 1 / 4λ wavelength. For example, the 2.4G WIFI wavelength is 125mm, and the antenna will use a length of about 20~30mm, which can not only minimize the space requirements, but also meet the needs of users in the horizontal direction. Requirements for RF signal strength. However, compared with the external antenna, the gain and directivity of the onboard antenna are relatively poor. When there are metal and silver-plated materials on the structural parts, the attenuation of the onboard RF signal is more obvious. [0003] Therefore, how to design an antenna st...
