Example Embodiment

[0020] The embodiment of the present invention provides an antenna device and a terminal to solve the existing need to cut the metal frame or the metal back shell to realize the function of the antenna, which brings about the deterioration of product appearance consistency and reliability, and the increase in cost. problem.
[0021] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0022] Detailed descriptions are given below.
[0023] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used Describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments described herein can be implemented in a sequence other than the content illustrated or described herein.
[0024] See figure 1 , figure 1 It is a diagram of an embodiment of the antenna device of the present invention. The antenna device may include a metal frame 1, a clearance area 3 is provided between one end of the metal frame and the circuit board 2 of the terminal, and a radio frequency module arranged on the circuit board A feed point 4 is connected to the feed point, a feed metal trace 5 is connected to the feed point, one end of the feed metal trace is connected to the metal frame, and one side of the clearance area is also provided with impedance The loading device 6 has two ends of the impedance loading device respectively connected to the circuit board and the metal frame.
[0025] It can be seen that by flexibly using a part of the metal frame as an antenna, and using an impedance loading device, the metal frame can be used as an antenna without any processing such as slitting and cutting. The impedance loading device can be used to adjust the loading impedance to facilitate the antenna The radio frequency module is connected with a feeding point, and the feeding metal trace connected to the feeding point feeds the metal frame, so as to realize the antenna of multiple communication frequency bands. Compared with the metal back shell or the metal frame, Can reduce costs, improve product reliability and appearance consistency.
[0026] Optional, see figure 2 , figure 2 It is another embodiment diagram of the antenna device according to the embodiment of the present invention. The impedance loading device includes a capacitor 62 and/or an inductor 61, and the capacitor and/or inductor and the metal frame form a resonant structure.
[0027] It is understandable that the function of the impedance loading device is mainly used to adjust the loading impedance to achieve impedance matching during antenna transmission. The impedance connection device can be composed of capacitors or inductors or capacitors plus inductors in three ways. The wiring conditions are adjusted adaptively.
[0028] Optionally, the capacitor and/or the inductance are lumped parameter capacitors and/or lumped parameter inductors.
[0029] Optionally, the capacitor and/or the inductance are distributed parameter capacitors and/or distributed parameter inductors.
[0030] It is understandable that for the impedance loading device, the capacitor can be a lumped parameter capacitor or a distributed parameter capacitor, and the inductance can be a lumped parameter inductor or a distributed parameter inductor. If the impedance loading device has both capacitance and inductance, the capacitance and inductance It can be lumped parameter type or distributed parameter type.
