Abstract

The invention relates to an LTE high-gain wideband antenna. Through PCB double-surface copper-clad plate characteristics and production technology, a set of antenna is divided into two parts and the two parts are arranged to an A surface and a B surface of a rectangular PCB double-surface copper-clad plate, the dimension of which is 110.2 mm*26.0 mm*0.8 mm respectively. In the prior art, similar products are large in size, and gain thereof is only 5-6 dbi. The beneficial effects of the antenna are that 1) the antenna is small in size, and the size is only 110.2 *26 *0.8 mm; and 2) performance is improved obviously, that is, the gain reaches 8 dbi.

Description
