Abstract

The invention provides an antenna which comprises metal wires, an antenna feeder and a power supply connector. The metal wires are arranged on a PCB (printed circuit board) and are connected with the antenna feeder at feed points, the antenna is provided with a reactance component which is arranged on a certain surface of the PCB, the certain surface can be opposite to the surface where the feed points are located, or the reactance component and the feed points can be arranged on the identical certain surface of the PCB; the reactance component is conducted when frequencies of radiofrequency signals of the antenna are low, and is disconnected from the antenna when the frequencies of the radiofrequency signals of the antenna are high; alternately, the reactance component is disconnected from the antenna when the frequencies of the radiofrequency signals of the antenna are low, and a control switch of the reactance component is conducted when the frequencies of the radiofrequency signals of the antenna are high. The antenna has the advantages of wide antenna coverage frequency bands and high radiation efficiency.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an antenna. Background technique [0002] With the popularity and development of mobile terminals, there is an urgent requirement for antenna miniaturization. The multiple-input multiple-output MIMO antenna system necessary for the current 4th band mobile communication 4G has put forward new requirements for antenna design and evaluation: [0003] On the one hand, in today’s increasingly demanding market for products, users require small and exquisite ID design and high-quality user experience; [0004] On the other hand, the long-term evolution technology LTE700 frequency band with a lower frequency requires a larger antenna size, dual antennas of the MIMO antenna system, and requirements for high-performance radio frequency indicators (high isolation, low correlation coefficient, etc.) lead to an increase in product size. [0005] The contradiction between these two aspe...
