Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that to ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, some deformations and improvement can also be made.
These belong to protection domain of the present utility model.
The utility model embodiment provides a kind of NFC and radio frequency two-in-one antenna based on metal shell construction, including
Metal shell construction, NFC circuit module and RF circuit module, described metal shell includes metal-back body, top metal
Frame and two side frames；The metal-back body is to being plastic cement region between top metal frame；Have two on top metal frame
Individual breakpoint, the first breakpoint two ends connect respectively an inductance element, inductance element other end connection NFC circuit module；Second breaks
One inductance element of point two ends series connection.So, top metal frame, inductance element, two side frames and metal back cover body structure
Into loop checking installation, as NFC coupling regimes.Partly there are two tie points between the breakpoint of top metal frame two, one is to connect
