Description

Integrate the structure of sensing element electrodes and antenna

technical field

The invention relates to a structure for integrating electrodes and antennas of sensing components, in particular to a structure that integrates electrodes and antennas of sensing components into a single component, and at the same time solves the problem that the distance between electrodes and antennas of sensing components is too close , and the structure of the integrated sensing component electrode and antenna that makes the two signals interfere with each other.

Background technique

Most electronic devices with integrated wireless functions, such as laptop computers, smart phones, and mobile phones, use antennas to transmit and receive radio frequency signals. The use of these electronic devices will generate electromagnetic waves, and if the electromagnetic waves are too high, it will have a bad effect on the human body. Therefore, in order to solve this problem, a specific absorption rate (SpecificAbsorbRate, SAR) of electromagnetic wave energy has been developed as a mobile phone to protect the human body against electromagnetic waves. The degree of absorption is used as a judgment criterion, and sensing components such as proximity sensing components are used to detect whether a human body is approaching on these electronic devices. When the proximity sensing component detects that a human body is approaching, the power output of the antenna will be adjusted. Furthermore, the power of the antenna conforms to the electromagnetic wave energy absorption rate. However, in the traditional design, the antenna and the proximity sensing component are respectively arranged on different conductor structures, and are two independent components, and the distance between the two is set as far as possible, so as to prevent the radio frequency of the antenna The signal and the sensing electrode signal of the proximity sensing component will interfere with each other, but today's electronic devices all require short, light and thin designs, so how to configure them in a limited space is the main focus of the industry.

Therefore, how to arrange the antenna and the sensor component in the limited space of the electronic device, so that the signals of the two will not interfere with each other, is indeed a problem that the industry needs to solve urgently.
