Problems solved by technology

However, the increase of near-field communication functions will inevitably introduce corresponding near-field communication modules and antennas dedicated to near-field communication, which will increase the size of the circuit and eventually increase the size of terminal electronic products
Technicians have found that there are at least the following problems in terminal electronic products that generally include near-field communication functions: adding near-field communication circuit modules and near-field communication-specific antennas, while traditional near-field communication-specific antennas use flexible printed circuit boards plus ferrite way to achieve, occupying a large space, resulting in an increase in the volume of terminal electronic products

Abstract

The invention discloses a communication antenna device, and belongs to the field of communication equipment. The device comprises a first communication module, an antenna module and an inductor; the first communication module comprises a first communication chip and a first matching circuit; the antenna module at least comprises a communication antenna for transmitting a second communication signal; the frequency of the first communication signal is smaller than that of the second communication signal; and the communication antenna is connected in series with the first matching circuit through the inductor. According to the technical scheme provided by the invention, the first communication signal and the second communication signal share the antenna module for transmission, and the first communication signal is not interfered by the second communication signal, so that the circuit volume is saved, the circuit is simplified, the size of a terminal electronic product is reduced, and the radiation efficiency of the antenna is improved.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a communication antenna device. Background technique [0002] With the development of science and technology, the functions of terminal electronic products are becoming more and more powerful. Many terminal electronic products integrate near-field communication technology, which brings convenience to people's life in payment, transportation, identity verification and other aspects. However, the increase of near-field communication functions will inevitably introduce corresponding near-field communication modules and antennas dedicated to near-field communication, which will increase the size of the circuit and eventually increase the size of the terminal electronic product. Technicians have found that there are at least the following problems in terminal electronic products that generally include near-field communication functions: adding near-field communication circuit mo...
