Abstract

The invention provides an adjustable antenna device capable of detecting an approaching object. The adjustable antenna device capable of detecting the approaching object includes a first radiator, a ground portion, a second radiator, a proximity sensing chip, and a variable capacitor. The first radiator comprises a signal feeding point, so that an antenna signal is fed to the first radiator. The variable capacitor and the proximity sensing chip are arranged in the range of the first radiator, the ground portion, and the second radiator, and used to adjust the frequency of the antenna. In addition, a plurality of switches and capacitor adjustment blocks can be used instead of the variable capacitor. The capacitance adjustment blocks and the ground portion are arranged on different surfacesof a circuit board. The areas of the capacitor adjustment blocks are different from each other. Switches are used to selectively electrically connect one of the capacitance adjustment blocks and the second radiator, so as to adjust the frequency of the antenna device. The antenna device provided by the invention can detect the approaching object and adjust the frequency.

Description

technical field [0001] The present invention relates to an adjustable antenna device with the function of detecting object approaching, and in particular relates to an adjustable antenna device with the function of detecting object approaching suitable for narrow spaces. Background technique [0002] With the rapid development of communication technology, various communication products, such as wireless access points (Wireless Access Points), smart phones and notebook computers have gradually become a part of human life. Most of these communication products have an antenna device to realize the function of wireless transmission, so as to meet the needs of consumers. In addition, current communication products usually use small-sized antenna devices to make the communication products miniaturized and integrate more functions. For example, current communication products usually integrate an object proximity detection function to improve the performance of the antenna device. ...
