Problems solved by technology

Furthermore, in order to make the induction more accurate, the conventional antenna device needs to use several proximity sensors or several capacitors with several layers of conductive layers to produce induction in conjunction with the proximity sensor. There is still room for innovation and improvement.

Abstract

The invention provides an access-sensing antenna device including an antenna structure and an access sensing modulus. The antenna structure comprises a first and a second conductors, and a capicator assembly and an inductance assembly electrically connected to the second conductor. The second conductor is coupled with the first conductor through RF signals to serve as an capicatance electrode that senses external objects. When the second conductor serves as a capicator electrode, capicatance value that is changed according to distance relative to the external objects is generated. When the capicatance assembly is used for isolating the second conductor to form the capicatance electrode, the capicatance assembly is arranged through the detection signal on the second conductor; and when the inductance assembly, for isolating the first conductor, is coupled to the second conductor, is arranged through the RF signal of the second conductor. The access sensing modulus is electrically connected to the inductance assembly and further is electrically connected to the second conductor and the capicator assembly through the inductance assembly.

Description

[0001] priority [0002] The present invention takes the Taiwan patent whose application date is September 11, 2015 and whose application number is 104130110 as priority. technical field [0003] The present invention relates to an antenna device, and in particular to a proximity sensing antenna device and its antenna structure. Background technique [0004] In order to control the amount of radiation generated by handheld electronic devices on the human body, when designing handheld electronic devices, it is generally necessary to add a proximity sensor (P-sensor) at the main antenna position of the wireless wide area network (WWAN) to sense the human body approach, and then activate the protection mechanism of power reduction to reduce the radiation level generated by the handheld electronic device. Furthermore, in order to make the sensing more accurate, the conventional antenna device needs to use several proximity sensors or several capacitors with several layers of c...
