A Novel Design of Printed Yagi Antenna

In this paper, a novel design of printed Yagi antenna is presented. To improve the input and radiation performance, the driver and directors are modified. And the simulated results are compared with the measured data. This proposed antenna achieves a measured 10% bandwidth for VSWR<;2, better than 11.9 dB front-to-back ratio, and 8.3 dB absolute gain across the operating bandwidth. Furthermore, the proposed Yagi antenna array is simulated. And the mutual coupling effect is analyzed.
