中文摘要：
提出了一种采用复合左右手传输线馈电的新型微带阵列天线．该天线利用左手传输线的相位超前特性来补偿传统的右手传输线所具有的相位滞后，从而保证了天线单元之间的同相位馈电，避免了因相位延迟导致的天线波束偏移，并进一步提高了天线的增益．仿真与实际测试证明：与同类型天线相比，该天线具有尺寸小、频带宽和馈电网络设计简单等优点，可在微波系统中实际使用．
英文摘要：
A novel microstrip antenna array fed with composite right/left- handed transmission line （CRLH-TL） was presented. The antenna utilizes the positive phase delay of the CRLH-TL to compensate the negative phase delay of the ordinary fight-handed transmission line so that the equal phase feeding between the elements of the antenna is guaranteed. As a resuit, the offset of the radiation beam of the antenna owing to the phase delay is avoided and the gain is increased. The simulation and experimental results indicate that this antenna is of advantages of small dimension, broad frequency bandwidth and easy design for the feeding structures compared with the same type of conventional antenna, and it is applicable to the practical microwave system.
