Problems solved by technology

However, the current multi-functional antenna does not take the NFC antenna into consideration. If the NFC function is added, a new antenna structure needs to be designed separately, which is difficult to achieve for thin and light mobile phones.

Abstract

The invention discloses an antenna structure of an NFC antenna realized on a terminal. The antenna structure comprises a first loop antenna and a second loop antenna, wherein the first end of the first loop antenna is a first grounding point; the second end of the first loop antenna is a first feed point; the first end of the second loop antenna is a second grounding point; the second end of the second loop antenna is a second feed point; the first loop antenna and the second loop antenna are adjacent to each other, wherein the first feed point and the second feed point are adjacent to each other, or the first grounding point and the second grounding point are adjacent to each other; the first loop antenna and the second loop antenna jointly form the NFC antenna; the NFC antenna feeds a first signal from the first feed point and feeds a second signal from the second feed point; and the first signal and the second signal are opposite in phases.

Description

technical field [0001] The present invention relates to antenna technology, in particular to an antenna structure for realizing a Near Field Communication (NFC, Near Field Communication) antenna on a terminal. Background technique [0002] With the intelligent development of mobile phones, more and more functions need to be supported by mobile phones. Some functions need to be supported by corresponding antennas, for example, realize the wireless Internet access function through the Wireless Fidelity (WiFi, Wireless Fidelity) antenna, realize the GPS positioning function through the Global Positioning System (GPS, Global Positioning System) antenna, and realize the GPS positioning function through the communication antenna. Realize the function of mobile communication. [0003] For a mobile phone, it has a limited size and needs to be thin and light in design. If each function requires a separate antenna, it will inevitably increase the size of the mobile phone. Therefore,...
