摘要

本文提出了一种2.2 GHz宽带单平面准八木天线的优化设计，并提出了一种基于贴片而不是偶极子作为驱动元件的新结构——准八木贴片天线。之所以选择这个中心频率，是因为准八木天线的宽带特性，使其能够在1.9 GHz、gsm -美国标准、2.4-2.5 GHz、802.11 b WLAN和蓝牙下工作。由于回波损耗和辐射方向图的计算精度较高，因此采用时域有限差分法(FDTD)进行仿真。回波损耗测量结果表明，该设计适合于无线通信。

Patches driver on the quasi-Yagi antenna: analyses of bandwidth and radiation pattern

This work presents the optimization of a broadband uniplanar quasi-Yagi antenna at 2.2 GHz and a novel structure, called the quasi-Yagi patch antenna, based on patches instead of a dipole as driver element. This center frequency was chosen due to wideband characteristic of the quasi-Yagi antenna to allow its operation at 1.9 GHz, GSM-USA standard, as well 2.4-2.5 GHz, 802.11 b WLAN and Bluetooth. The simulation results were obtained using FDTD (finite difference time domain method), due to great accuracy in calculating return loss, and radiation pattern. The return loss measurements indicate that the novel design is suitable for wireless communications.
