YAGI-UDA ANTENNA (YAGİ ANTENLERİ-PART2)

Hello! We reviewed Yagi antennas in this video. Thank you for watching me!

In the previous video, we gave yagi-uda antennas as an example of directional antennas. We will now examine it in more detail. Let's first examine the history of these antennas. Yagi antennas were originally designed and developed by Yagi, a professor at the university, and his assistant, Uda. Yagi antennas are antennas that emit longitudinal radiation and have a narrow bandwidth. Frequency ranges belong to the VHF and UHF bands, and have a frequency operating range of 30MHz and 3GHz. A basic level yagi antenna is given in this image. This yagi antenna consists of passive and active circuit elements. For example, here is the reflector, the passive circuit element with the longest length. Here, there is a driven element and it is an active circuit element. Finally, directors are our passive circuit elements. If passive circuit elements are increased in a yagi antenna, the antenna gain increases while the bandwidth decreases. Now let's examine what the reflector does. It directs the electromagnetic waves sent from the transmitter towards the dipole. The driven element determines the antenna polarization and center frequency. Finally, routers have different distances and lengths from each other. The more routers, the higher the antenna gain.
