Abstract

The invention discloses an antenna, which comprises a printed circuit board, a clearance area and a feed source being arranged on the printed circuit board; a ground plane arranged on the printed circuit board and provided with a first ground point and a second ground point on the ground plane; a first antenna radiator arranged in the clearance area, connected with the feed source and grounded through the first ground point; a metal frame surround that outer periphery of the printed circuit board and spaced apart from the ground plane is provided with a gap, the metal frame comprises a first connection point and a second connection point, a feed source is further connected with the first connection point, the second connection point is grounded through the second ground point, and a secondantenna radiator is formed by the metal frame from the first connection point to the second connection point. In the structure above, the metal frame is a complete closed loop, and no breaking jointis arranged, so that the electronic device using the antenna has better strength and better appearance texture. The present application also provides an electronic device comprising the antennas above.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna and an electronic device. Background technique [0002] Antennas are installed on electronic devices such as mobile phones and tablet computers for communication. At present, the antennas of electronic devices such as mobile phones are usually provided with breaks in the metal frame of the metal shell to meet the performance requirements of the antenna frequency band. However, such broken seams will affect the overall appearance of the mobile phone and the appearance texture of the entire electronic device, and the processing cost of the broken seams is high. On the other hand, the broken seam has high requirements on the width of the broken seam in the process of processing. If the width is too large, it will affect the appearance and the strength of the electronic device; otherwise, the width will cause mutual coupling between the parts on both s...
