Abstract

Applications in 3G, WLAN and Bluetooth are actually the largest area in wireless communications, especially for antenna designers. Due to that, in this paper a broadband planar antenna based on the classic Yagi-Uda dipole antenna and projected to the range of frequencies that includes 1.8 GHz, 1.9 GHz, and 2.45 GHz is presented. This "tilted dipole, quasi-Yagi antenna" achieves a measured 41% bandwidth for VSWR<2 a directivity of 5.5 dBi and an efficiency of 70-85%. In addition, a comparison between this antenna and a classical quasi-Yagi is done. The agreements between simulated and measured results for return loss are satisfactory.

一种新型倾斜偶极子准八木天线，用于3G和蓝牙应用

3G、WLAN和蓝牙的应用实际上是无线通信中最大的领域，特别是对天线设计者来说。为此，本文在经典八木偶极子天线的基础上，设计了一种1.8 GHz、1.9 GHz和2.45 GHz频段的宽带平面天线。这种“倾斜偶极子准八木天线”在VSWR<2，指向性为5.5 dBi的情况下实现了41%的测量带宽和70-85%的效率。此外，还将该天线与经典的准八木天线进行了比较。回波损耗的模拟结果与实测结果吻合较好。
