Radio frequency device and wireless communication device

Abstract

The invention provides a radio frequency device and a wireless communication device. The radio frequency device is used for a wireless communication device, and the radio frequency device includes a ground connection component, an antenna, a ground connection end, a capacitance induction component and at least one capacitor. The ground connection component is used for providing ground connection; the antenna includes a radiator, a signal feed-in component, the signal feed-in component is coupled with the radiator, and is used for transmitting a radio frequency signal to the radiator so as to launch the radio frequency signal through the radiator; the ground connection end is coupled with the ground connection component; the capacitance induction component is electrically connected with the radiator of the antenna, and is used for inducting an environment capacitance within a specific range through the radiator; at least one capacitor is in connection between the ground connection end of the antenna and the ground connection component, and is used for blocking-up a direct current signal path from the ground connection end to the ground connection component. The radio frequency device can avoid the influence on radiation efficiency of the antenna, and reduce the cost of design and production, and bring convenience to parts management.

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 and can reduce design and production costs. 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 Absorption Rate, SA...

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
