Antenna Theory - Yagi-Uda Antenna. Yagi-Uda antenna is the most commonly used type of antenna for TV reception over the last few decades. The frequency range in which the Yagi-Uda antennas operate is around 30 MHz to 3GHz which belong to the VHF and UHF bands.

The goal of this project is to design and build high gain, low cost, low profile antenna that can be. A Yagi–Uda antenna, commonly known as a Yagi antenna, is a directional antenna consisting of multiple parallel elements in a line, usually half-wave dipoles made of metal rods. Geometry of Yagi Antennas. The basic geometry of a Yagi-Uda antenna is shown below in Figure 1. Figure 1. Geometry of Yagi-Uda antenna. The Yagi antenna consists of a single 'feed' or 'driven' element, typically a dipole or a folded dipole antenna. This is the only member of the above structure that is actually excited (a source voltage or current applied). Antenna Theory 8 Antenna can also be termed as an Aerial. Plural of it is, antennae or antennas. Now-a-days, antennas have undergone many changes, in accordance with their size and shape. There are many types of antennas depending upon their wide variety of applications. Following pictures are examples of different types of Antennas. Yagi antenna theory - the basics. One of the major keys to understanding Yagi theory is a knowledge of the phases of the currents flowing in the different elements of the antenna. The parasitic elements of the Yagi antenna operate by re-radiating their signals in a slightly different phase to that of . Loading Main menu. The Yagi Uda antenna. Described and published by S. Uda and H. Yagi in the s. Did not receive full acclaim in the United States until Driven element is excited directly via feedline, all other elements excited parasitically.

Analysis with VNA Shows resonance frequency, input impedance, SWR Incredibly useful for tuning Analysis Signal Generator and Spectrum Analyzer Sender: signal generator (tuned to GHz) + antenna. commercial GHz dipole antenna (reference) our Yagi antenna. The Yagi antenna sometimes called the Yagi-Uda RF antenna is widely used where specified gain and directivity are required. The Yagi-Uda antenna is one of the most successful RF antenna designs for directive antenna applications. This antenna is used in a wide variety of applications where an RF antenna design with gain and directivity is required.
