Tuning of Yagi Uda Antenna with Gain Enhancement at 300 Mhz and 2.4 Ghz Bands For Wi-Fi Application

In this paper, a tuning of several Yagi-Uda antennas in the frequency range of 300 MHz and 2.4 GHz band for uniform and non-uniform spacing between directors and maintaining this spacing between the elements to enhance the gain is discussed. A Yagi-Uda antenna with closely spaced directors is proposed for achieving appreciable gain as reducing the spacing results in physically compact size. Further, we seek other techniques such as folded dipole Yagi-Uda antenna and increasing the radius of reflector. The computer simulation was performed and results were compared with traditional Yagi-Uda antenna with the aim at tuning it for Wi-Fi application.
