Problems solved by technology

Additional receivers or sensors will affect the efficiency of the antenna, causing the operating frequency band to be narrowed. In other words, the antenna that is originally suitable for broadband requirements will cause the operating frequency band to be narrowed due to the additional receiver or sensor.
In this case, for different communication systems with similar frequency band requirements, it is necessary to design suitable antennas separately. In addition to increasing design and production costs, it is also unfavorable for parts management

Embodiment Construction

[0038] In order to take into account the two requirements of reducing interference and maintaining antenna performance, the applicant of this case has provided a radio frequency device and a wireless communication device for judging the proximity of a human body in Taiwan Patent Application No. 100142160, which does not require additional receivers or sensors , but use the radiator of the antenna to sense the ambient capacitance value in a specific range, so it can avoid affecting the radiation efficiency of the antenna. Among them, for different antenna structures, China Taiwan Patent Application No. 100142160 has disclosed a variety of setting methods for capacitive sensing components, one of which is that the capacitive sensing component and the signal feeding component share a node, and the capacitive sensing component passes through common node and electrically connected to the radiator (refer to Chinese Taiwan Patent Application No. 100142160 figure 2 A. figure 2 C. ...

Abstract

The invention provides a radio frequency apparatus and a wireless communication apparatus. The radio frequency apparatus is used for the wireless communication apparatus, the radio frequency apparatus comprises an antenna, a capacitive induction assembly, a connecting assembly, a direct current blocking assembly, and an induction auxiliary assembly, the antenna comprises a radiator and a signal feed-in assembly, the connecting assembly comprises a first terminal, a second terminal, and a third terminal mutually switched on, the first terminal is electrically connected to the radiator, the direct current blocking assembly is electrically connected between the second terminal of the connecting assembly and the signal feed-in assembly, the induction auxiliary assembly is electrically connected between the third terminal of the connecting assembly and the capacitive induction assembly, the induction auxiliary assembly comprises a high frequency blocking assembly and at least one capacitor, and the at least one capacitor and the high frequency blocking assembly are connected in series and are electrically connected between the third terminal of the connecting assembly and the capacitive induction assembly. According to the radio frequency apparatus and the wireless communication apparatus, the radiator of the antenna is employed to induct the environmental capacitance value in a specific range, the influence on the radiation efficiency of the antenna can be avoided, and the design and production costs can be further reduced.

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 design and production costs and achieve modular design. 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 value of the specific absorption rate (Specific...
