Embodiment Construction

[0064] In order to take into account the two requirements of reducing interference and maintaining antenna performance, the invention utilizes the radiator of the antenna to sense the environmental capacitance value in a specific range, and adjusts the energy of the wireless signal accordingly. Different communication systems with different frequency band requirements only need to design a single antenna, which can reduce design and production costs and facilitate parts management. In addition, the present invention also utilizes the DC blocking component and the high frequency blocking component to increase the effective sensing area of ​​the sensing component, increase the sensing distance and reduce the influence of the sensing component on the radiation efficiency of the antenna. In the following, the concepts of the present invention will be described in two categories according to different antenna forms.

[0065] First, for antennas with a DC connection path between the...

Abstract

A radio frequency device and a wireless communication device. The radio frequency device contains a grounding assembly used for providing ground connection, an antenna which contains a radiator, a signal feed-in assembly for transmitting a radio-frequency signal to the radiator so as to transmit the radio-frequency signal through the radiator and a ground terminal for coupling the grounding assembly, a capacitive sensing assembly for sensing an environmental capacitance value within a specific range through the radiator, a first DC blocking assembly for blocking a DC signal path from a ground terminal of the antenna to the grounding assembly, a second DC blocking assembly for blocking a DC signal path from the radiator to the signal feed-in assembly of the antenna, and a high-frequency blocking assembly which is electrically connected between the radiator and the capacitive sensing assembly and is used for blocking a high-frequency signal path from the radiator to the capacitive sensing assembly. According to the invention, radiant efficiency is not influenced, design and production costs can be reduced, and it is beneficial to parts management. The radio-frequency device has characteristics of small size, high efficiency, high environmental suitability and low interference.

Description

technical field [0001] The invention relates to a radio frequency device and a wireless communication device, in particular to a radio frequency device and a wireless communication device which can avoid affecting the radiation efficiency of an antenna, reduce the size of the radio frequency device and increase the sensing distance. Background technique [0002] A wireless communication device transmits or receives radio waves through an antenna to transmit or exchange radio signals, and then access a wireless communication system. Radio wave is a high-frequency oscillating sine wave signal. Therefore, countries around the world have certain regulations on its energy. The main purpose is to avoid affecting users or interfering with the operation of other wireless communication devices. For example, the International Commission on Non-Ionizing Radiation Protection (International Commission on Non-Ionizing Radiation Protection) recommends that the specific absorption rate (Spe...
