Title: REFLECTIVE ARRAY ANTENNA AND COMMUNICATION DEVICE
Abstract:
A reflective array antenna and a communication device. The antenna comprises a feed array, a secondary reflective surface and a primary reflective array, wherein the feed array can emit an electromagnetic wave in a first polarization direction; the secondary reflective surface is used for reflecting the electromagnetic wave, emitted by the feed array, in the first polarization direction, and can make an electromagnetic wave in a second polarization direction penetrate; the primary reflective array is used for converting the electromagnetic wave, reflected by the secondary reflective surface, in the first polarization direction into the electromagnetic wave in the second polarization direction, and reflecting same. In the technical solution, a secondary reflective surface can be used to reflect an electromagnetic wave in a first polarization direction, and by means of an electromagnetic wave in a second polarization direction, the secondary reflective surface can be made larger, and the electromagnetic wave emission of a primary reflective array cannot be blocked, so that the required range of beam scanning can be satisfied in a relatively low-cost way, and the requirements of an application for a directional pattern can be satisfied.
