摘　　要：提出了一种具有多频特点的新型圆环嵌套印刷天线,该天线由不同直径的圆环嵌套得到。通过电磁仿真软件CST Microwave Studio进行仿真研究,结果表明嵌套圆环的外径、宽度和嵌套数目可以对其通频带中心频率、频带宽度和通频带数目进行控制。设计出了具有2.4 GHz,3.5 GHz,5.2 GHz,5.8 GHz四个通频带的共面波导馈电的单极印刷天线和以平衡微带线馈电的对称振子天线。制作了天线实物并在微波暗室中进行测试,测试结果与仿真吻合较好,该天线具有近似独立的频率可控性和较小的尺寸,可用于WLAN和WiMAX等领域。A novel multiband printed antenna with ring-nested is proposed. The antenna is nested with rings which are in different radius and the antenna model is simulated and analyzed by CST Microwave Studio@. The simulated results show that the central frequency of the pass-band, as well as the bandwidth and the number of pass-bands can be controlled by the outer radius and width of the nesting rings and the rings＇ number. A monopole printed antenna and a dipole antenna operating in bands of 2.4 GHz, 3.5 GHz, 5.2 GHz and 5.8 GHz has been designed, which are fed by the coplanar waveguide and the balanced microstrip line respectively. Prototypes of the two antennas are manufactured and measured in the anechoic chamber. The measured results show good agreement with the simulated. Moreover, the antennas possess the approximately independent frequency controllability and miniature size, which can be applied in the WLAN and WiMAX areas.
