Abstract

The invention discloses an antenna, comprising: an antenna bracket and an antenna radiator, the antenna radiator includes an inductor, an electric feed point, and a ground feed point, and the inductor, the electric feed point, and the ground feed point are arranged side by side The connection line between the inductance and the ground feed point is arranged parallel to the trace on the antenna support, and the distance between the inductance and the ground feed point connection line is adjustable. By adopting the embodiment of the present invention, not only the radiation efficiency of the antenna can be guaranteed, but also the low-frequency bandwidth can be widened.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an antenna. Background technique [0002] With the popularization of LTE (Long Term Evolution, Long Term Evolution) technology, the bandwidth required to be supported by the antenna is getting wider and wider. But at the same time, users have higher requirements on the appearance of electronic equipment, which makes electronic equipment more and more miniaturized and thinner. In this case, the antenna space of the electronic equipment is also being gradually compressed, and the antenna space is basically proportional to the bandwidth. Therefore, it becomes a difficult problem to achieve a wider bandwidth in a smaller antenna space. [0003] The current mobile phone antenna is divided into two types: external and built-in. The built-in mobile phone antenna is placed inside the mobile phone, such as IFA (Inverted-F Antenna, inverted F antenna) type antenna, of which PIFA (Plan...
