Abstract

The invention relates to an antenna unit which comprises a basal plate, a first grounding part, a second grounding part, a first radiation part and a second radiation part, wherein the basal plate is provided with a surface, a grounding face formed on the surface as well as a first feed-in point and a second feed-in part which are formed on the surface; the first grounding part extends outwards from a first end of the grounding face; the shape of the second grounding part is similar to that of the first grounding part, and the second grounding part extends towards a direction opposite to the first grounding part from the first end of the grounding face. The invention can achieve a diversity effect by the first grounding part and the first radiation part as well as the second grounding part and the second radiation part, thereby being capable of reducing the situation of a bad signal caused by the multi-path effect to a large extent and increasing the effectiveness of the whole antenna.

Description

technical field [0001] The present invention relates to an antenna device, in particular to an antenna device that adopts a multi-antenna design to achieve a diversity effect. Background technique [0002] WiMAX is a technology that is currently in full swing. Its maximum transmission speed can reach 75Mbit / s, which is dozens of times faster than the previous wireless transmission speed. Its maximum transmission distance can reach 50km, so it can reduce the construction of base stations and save the cost of wireless networks. cost. [0003] Due to its long transmission distance, the problem of multi-path interference is unavoidable, especially in cities where there are many buildings, the problem of multi-path interference is even more serious. Contents of the invention [0004] Therefore, the object of the present invention is to provide an antenna device that is applied to WiMAX and solves the problem of multi-path interference. [0005] Therefore, the antenna device o...
