摘要：
A cavity-backed slot antenna array using a single waveguide-fed subarray is proposed to reduce feed-line loss, increase radiation efficiency, and make the feed network simple. A subarray consists of 2 X 4 slot elements backed by a single cavity. By proper choice of dimensions, it is shown that the proposed antenna has the characteristics a high radiation efficiency and broad frequency bandwidth. The antenna characteristics for the array antenna with 256 elements are measured in the Ku-band. A single cavity-backed subarray has a gain of 18 dBi. The gain of the total antenna at-ray (256 elements) is more than 33 dBi. (C) 2004 Wiley Periodicals, Inc.
