本文介绍了一种设计和实现频率扫描印刷阵列天线的新概念。阵列天线由8个反谐振偶极子组成，中心频率为6 GHz，由对称（平衡）微带馈电。阵列天线的元件之间的波长距离是λ//sub k//2。天线通过SMA连接器馈电，巴伦通过锥形实现。发现波束扫描是均匀的和连续的/spl Delta//spl θ/=49.8/spl deg/，频率变化范围从9.4 GHz到6.6 GHz（/spl plusmn/10%的中心频率）。
A new concept for the design and realisation of a frequency scanning printed array antenna is described. The array antenna consists of 8 antiresonant dipoles fed by a symmetrical (balanced) microstrip at a central frequency of 6 GHz. The distance in wavelengths between the elements of the array antenna is /spl lambda//sub k//2. The antenna is fed through a SMA connector and balun realised by tapering. The beam scanning is found to be uniform and continuos /spl Delta//spl theta/=49.8/spl deg/, with a frequency variation in the range from 9.4 GHz to 6.6 GHz (/spl plusmn/10% of the central frequency).
