Abstract

The embodiment of the invention discloses a broadband PIFA antenna, which comprises an antenna radiator, a first feeder line and a second feeder line, and is characterized in that the antenna radiatorcomprises a first radiation branch, a second radiation branch and a third radiation branch which are respectively used for radiating the energy of a first frequency band, a second frequency band anda third frequency band; a coupling gap exists between the second radiation branch and the third radiation branch and is used for expanding the bandwidth corresponding to the third frequency band; thefirst feeder line is used for connecting the first radiation branch with a first ground feeding point; and the second feeder line is connected with the second radiation branch and the third radiationbranch, one end of the second feeder line is connected with a feed point, and the other end of the second feeder line is connected with a second feed ground point. The embodiment of the invention further provides a communication terminal.

Description

technical field [0001] The present application relates to the technical field of electronic devices, and relates to, but is not limited to, broadband PIFA (Planar Inverted-Fantenna, Planar Inverted-Fantenna) antennas and communication terminals. Background technique [0002] With the rapid development of wireless communication technology, there are more and more demands for intelligent terminals. Among them, as the core component of signal transmission and reception, the antenna plays an important role, and is generally required to have the characteristics of small size and wide coverage. In 5G (5th generation mobile networks, fifth generation mobile communication technology) mobile terminals, the working frequency band of the antenna reaches 5GHz (gigahertz). Conventional PIFA antennas have problems of insufficient bandwidth and insufficient coverage. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a broadband PI...
