The invention discloses an antenna structure for a mobile phone terminal with a metal shell, which includes a metal shell for the mobile phone, and the metal shell for the mobile phone further includes: a metal front cover, which is provided with a ground and a signal terminal; and a metal back cover, which includes a first There is a slit between the back cover and the second back cover, and between the first back cover and the second back cover. Wherein, the first back cover includes a feeding point and a grounding point whose positions can be changed; the second back cover includes a feeding point and a grounding point whose positions can be changed; and the connection between the first back cover and the second back cover The site is connected to the ground on the front cover through the non-flap connector; the feed points of the first rear cover and the second rear cover are connected to the signal terminal on the front cover through the non-flap connector. Compared with the prior art, the invention has a simple structure and is easy to manufacture, and solves the technical problem in the prior art that the back cover of the mobile phone cannot use metal in a large area.
Description
technical field [0001] The invention relates to mobile phone antenna design, in particular to an antenna structure of a metal shell mobile phone terminal. Background technique [0002] Today's mainstream built-in mobile phone antennas are multi-frequency monopole antennas, IFA antennas, and multi-frequency loop antennas. Electromagnetic energy, so that the built-in antenna loses its proper function. However, no matter from the perspective of mobile phone manufacturers or mobile phone users, the use of metal mobile phone back covers in a large area will be a development trend in the future. The first reason is that a phone with a metal back cover looks more textured and beautiful than a plastic back cover; the second reason is that a metal back cover is more durable and wear-resistant than a plastic back cover. Although some mobile phone back covers currently use metal materials in the area other than the antenna, there is still a strong market demand for the use of larger ...
