Abstract

The invention discloses a combined antenna and electronic equipment, and aims at solving the technical problems of oversized area of a printed circuit substrate caused by the reference ground part of electromagnetic radiation type antennas in the prior art. The combined antenna comprises an electromagnetic induction type first antenna and an electromagnetic radiation type second antenna. The first antenna comprises a substrate with conductivity. The main body part of the second antenna is connected with the substrate of the first antenna, and the substrate acts as the reference ground part of the second antenna.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a combined antenna and an electronic device. Background technique [0002] With the rapid development of electronic technology, existing electronic devices can often use a variety of antennas to receive different signals, such as Bluetooth antennas, near field communication (English full name: NearFieldCommunication, abbreviation: NFC) antennas, wireless charging antennas, etc. . [0003] Among them, the NFC antenna and the wireless charging antenna belong to the application of electromagnetic induction, and the Bluetooth antenna belongs to the application of electromagnetic radiation. Among them, the antenna of the electromagnetic induction type does not need a reference ground part, while the antenna of the electromagnetic radiation type needs a reference ground part. [0004] In the prior art, in order to reduce the volume of the electromagnetic radiation antenn...
