Embodiment 1

[0022] The PIFA antenna provided in this embodiment can be applied to various electronic devices with a communication part, and the communication part is connected with the PIFA antenna to realize communication. The antenna provided in this embodiment includes an antenna grounding portion and an antenna radiation portion suspended above the antenna grounding portion, the antenna grounding portion includes a first antenna grounding portion and a second antenna grounding portion; the antenna radiation portion is connected to the second antenna grounding portion, Specifically, a feed point and a ground point are provided on the ground part of the second antenna, and the antenna radiating part can be connected to the corresponding feed point and ground point through wires. A slit is provided between the first antenna grounding part and the second antenna grounding part, and the slit overlaps at least a part of the antenna radiating part in the vertical direction, so that at least a...

Embodiment 2

[0028] In order to better understand the present invention, the present invention will be further described below by taking several specific PIFA antennas as examples.

[0029] See figure 2 As shown, the PIFA antenna shown in this figure includes a first antenna ground portion 21, a second antenna ground portion 22, and a gap 23 between the first antenna ground portion 21 and the second antenna ground portion 22, and the first antenna ground portion 21 It is completely isolated from the second antenna grounding part 22 by a gap 23; it also includes an antenna radiation part 24 (which includes a G-type antenna radiation unit, of course it can also be an inverted F type), and the antenna radiation part 24 and the second antenna grounding part 22 The feed point on the top is connected to the ground point; the slot 23 overlaps at least a part of the antenna radiation part 24 in the vertical direction; the first antenna ground part 21 can be used as a reflector; the PIFA can be ad...

Abstract

The invention discloses a PIFA antenna and an electronic device. The PIFA antenna comprises antenna grounding parts and an antenna radiation part hung above the antenna grounding parts. The antenna grounding parts include the first antenna grounding part and the second antenna grounding part. The antenna radiation part is connected with the second antenna grounding part. A seam exists between the first antenna grounding part and the second antenna grounding part and overlaps at least part of the antenna radiation part. In other words, at least one clearance area exists below the antenna radiation part of the PIFA antenna, and therefore the radiation efficiency of the PIFA antenna can be improved, and the performance of the electronic device with the PIFA antenna is improved; meanwhile, a low SAR value can be obtained, and the satisfaction degree of user experience can be further improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a PIFA antenna and electronic equipment. Background technique [0002] Nowadays, the number of various electronic communication terminals is increasing. On the one hand, everyone pays attention to the performance of electronic communication terminals and requires their signal to be good; on the other hand, they pay attention to the impact of radiation generated by electronic communication terminals on the human body. The compromise between radiation efficiency and SAR (electromagnetic wave absorption ratio or specific absorption rate) satisfies some international technical specifications and becomes a trend in antenna design for electronic communication terminals. PIFA antenna is an antenna widely used in various electronic communication terminals, please refer to figure 1 As shown, the existing OIFA antenna includes an antenna grounding part 11 and an antenna radiation part 12 arrange...
