Problems solved by technology

[0004] However, the current mobile terminals may need to be connected to Bluetooth-Wireless Local Area Networks (Blue Tooth-Wireless Local Area Networks, BT-WLAN), Global Positioning System (Global Positioning System, GPS), high-frequency long-term evolution (Long Term Evolution, LTE), etc. Work in multiple frequency bands, so the single-frequency IFA antenna combined with PCB is not suitable for mobile terminals that need to work in multiple frequency bands

Embodiment Construction

[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0057] The printed circuit board antenna and the metal frame antenna provided by the embodiments of the present invention can be set on mobile terminals that need to work in multiple wireless frequency bands, such as mobile phones, tablet computers and other mobile terminals. The multiple wireless frequency bands are, for example, BT-WLAN, GPS , T...

Abstract

The embodiment of the present invention provides a Print-circuit board antenna and terminal. The Print-circuit board antenna includes a Print-circuit board and a feed-back contact disposed on the Print-circuit board. The print-circuit board is covered by a copper layer. The copper layer is provided with a slot which is communicated with the outside of the print-circuit board. The copper layer is provided with a groove which is vertical to the slot. The slot is communicated with the groove. The copper layer on the two sides of the slot forms a first antenna and a second antenna from the slot to the two ends of the groove. The feed-back contact is used for forming a first resonant circuit with the first antenna and is used for forming a second resonant circuit with the second antenna. The resonant frequency between the first resonant circuit and the second resonant circuit are different.

Description

technical field [0001] Embodiments of the present invention relate to antenna technology, and in particular to a printed circuit board antenna and a terminal. Background technique [0002] With the development of mobile communication technology, mobile terminals are becoming more and more miniaturized, and more and more services are integrated in mobile terminals, so the antennas in mobile terminals are required to have compact size, sufficient bandwidth and multi-band Ability to work. [0003] At present, there is a single-frequency inverted F antenna (Inverted F Antenna, IFA) combined with a printed circuit board (Printed Circuit Board, PCB). The IFA antenna is a combination of a planar inverted F antenna (Planar Inverted F Antenna, PIFA) and a monopole A new type of antenna developed based on the characteristics of the (monopole) antenna. The IFA antenna also has the advantages of small monopole antenna size, high efficiency, sufficient bandwidth, and strong anti-interf...
