摘要：
Ultracompact metamaterial-based cavity (thickness N15) is proposed to realize a low secondary lobes level and highly directive phased array antenna. The cavity is fed by an array of four patch antennas designed to operate at around 9.5 GHz. The radiation patterns of the phased array's are compared with those of their respective metamaterial-based cavity antennas. The latter structures have lower secondary lobes and provide higher gain and directivity. Moreover, the cavities enhance the beam steering of the phased arrays. (C) 2009 Wiley Periodicals, Inc.
