Abstract

The invention discloses a converter. The converter includes a main body part that is continuously arranged on the outer edge of a mobile communication device, extends longitudinally, and covers the outer edge of the mobile communication device. Part of the printed circuit board arranged at intervals, extending from the printed circuit board to a first connection part and a second connection part connected to the main body part, located between the first connection part and the second connection part, connected the main body part and the first power feeding part and the second power feeding part of the printed circuit board, and the first control part and the second control part respectively controlling the first power feeding part and the second power feeding part, The first power feeding part and the second power feeding part are spaced apart.

Description

【Technical field】 [0001] The invention relates to a converter, in particular to an electromagnetic wave converter used in mobile communication equipment. 【Background technique】 [0002] The mobile phone with metal frame feels good and meets the user's aesthetic requirements. It is the technology chosen by many brand manufacturers for their flagship products. At the same time, the metal frame can be used as a part of the converter (antenna), so more and more mobile phone frames are used. part of the antenna. However, due to the limitation of antenna technology, metal-frame mobile phones are usually provided with breakpoints, and the breakpoints affect the appearance of the mobile phone. Therefore, it is rare to see a mobile phone with a full metal frame in the market. [0003] Chinese patent announcement No. CN201420551405 discloses a closed-loop (seamless) metal frame 3G antenna, which can realize working frequency bands of 824MHz-960MHz and 1710MHz-2170MHz. [0004] Pleas...
