Abstract

The present invention discloses an eccentric-feeding metal-encapsulated portable terminal antenna and belongs to the microwave technical field. A metal-encapsulated portable terminal antenna is designed on a dielectric substrate; and the terminal antenna is used for covering some frequency bands of GSM, UMTS and LTE and exciting a plurality of high-order modes through an eccentric feeding mode to increase working bandwidth. The antenna of the invention is small in size, so that the realization of the compatibility and coexistence of the antenna with the multi-antenna system of a future wireless communication system can be benefitted. The antenna can be realized through the processing techniques of existing mobile terminal antennas, such as injection molding, flexography and three-dimensional printing and a bright application prospect.

Description

technical field [0001] The invention relates to an eccentrically fed metal package portable terminal antenna, which belongs to the microwave field. Background technique [0002] With the extensive development of emerging services such as multimedia and the Internet, portable terminal antenna technology has been more and more widely used. It uses loop antennas to receive and send signals, effectively improving the problems of traditional terminal antenna technology and achieving better User experience is regarded as the core technology of next-generation mobile communication. [0003] The planar inverted-F antenna, inverted-F antenna and monopole antenna used in traditional handheld mobile devices have a larger surface current on the printed circuit board, which makes these types of antennas often used in handheld mobile devices easier to use when the user holds them. Bad experience. At the same time, handheld terminals are becoming more and more popular, and they begin to ...
