Abstract

The invention discloses an antenna and a wireless communication device. The antenna comprises an upper radiating plate, a frustum and a lower feed network layer. The upper radiating plate consists of a first substrate, a first conductive layer, and four feed points in a rotational symmetric mode; the first conductive layer is arranged at the upper surface of the first substrate; and the four feed points are formed on the first conductive layer and are connected with the lower feed network layer electrically. The frustum is provided with an accommodation space; and the upper radiating plate and the lower feed network layer are arranged in the accommodation space at an interval. According to the antenna disclosed by the invention, the four feed points in a rotational symmetric mode are used for feeding and the difference value between phases of the feed points are 90 degrees, so that the polarization characteristic can be realized. Moreover, with the antenna having the four feed points, the high phase center stability can be realized; the antenna having the four feed points has high symmetry, so that the roundness feature of the antenna can be realized and the high-precision measurement requirement can be met.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to an antenna and a wireless communication device. Background technique [0002] In related technologies, as GPS (Global Positioning System) antennas are rapidly and widely used in multiple fields such as navigation and surveying and mapping, GPS application fields are rapidly expanding, which strongly promotes the development of antenna technology. Generally, the GPS satellite constellation consists of 24 satellites, including 21 working satellites and 3 backup satellites. The satellites are distributed on 6 orbital planes, and 4 are evenly distributed on each orbital plane. The number of satellites above the ground level varies with time. It varies with the location, with a minimum of 4 and a maximum of 11. The GPS receiver must receive at least 4 satellite signals at the same time in order to use the distance from the receiver to the satellite to ...
