Abstract

With the rapid development of modern electronic technologies, antenna arrays are widely used in various wireless electronic systems. The common requirements for modern antenna arrays include wideband, high gain, low sidelobes or low cross-polarization levels. These requirements pose stringent requirements again on the fabrication precision of the array structure, the feeding precision of the feed network or error tolerance, etc., which are difficult to meet for conventional antenna arrays. By introducing a new degree of design freedom – the time, four dimensional antenna arrays can be formed, thus having much design freedom of antenna arrays. In this talk, the research background, basic principles and research status of the four dimensional antenna arrays are reviewed. Specifically, some practical topics and potential applications such as the sideband suppression, mutual coupling compensation, DOA estimation, secured communications, OAM communications and heterogeneous antenna arrays are covered.
