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...

Description
Summary: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.
