Yagi–Uda antenna - Wikipedia
A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; [1] these elements are most often metal rods (or discs) acting as half-wave dipoles. [2]
Yagi-Uda Antenna - Design, Components, Working and …
2024年2月26日 · The Yagi-Uda antenna, also known as Yagi antenna, catches TV and radio signals. Invented by Japanese scientists Hidetsugu Yagi and Shintaro Uda in the 1920s, it's great at sending signals in one direction. Useful for improving TV signals, ham radios, radar, and satellite communication.
YAGI ANTENNA DESIGN BASICS - Learn More About a Yagi (Beam) antenna!
The Yagi antenna's overall basic design consists of a "resonant" fed dipole (the fed dipole is the driven element and in the picture above and the second from the left side ), with one or more parasitic elements.
Yagi Uda Antenna : Basics, Working, Design and Its Applications
2022年5月11日 · Yagi Uda antenna is also termed as Yagi antenna which is a directional antenna that has either two or more parallel resonant antenna components acting as half-wave dipoles.
The Yagi-Uda Antenna - Yagi Antennas - Antenna Theory
The Yagi-Uda antennas typically operate in the HF to UHF bands (about 3 MHz to 3 GHz), although their bandwidth is typically small, on the order of a few percent of the center frequency. You are probably familiar with this antenna, as they sit on top of roofs everywhere.
How Does The Yagi Work? What’s A Vector And Vector Addition? Definition-A quantity with magnitude and direction. It can be represented by an arrow whose length indicates magnitude and whose tip represents direction. What’s About E-field Vector Addition? Eq= Iz * G(r, , q) Eq is directly proportional to the magnitude and phase of Iz.

The directional pattern of the Yagi-Uda antenna is highly directive as shown in the figure given below. The minor lobes are suppressed and the directivity of the major lobe is increased by the addition of directors to the antenna.
Design of Yagi-Uda Antennas Typical characteristics/parameters: • 4.3 dBi Directivity (Gain) 19 dBi • 15 Input Impedance 70 (w/out feed) • Bandwidth ≤ 2% (about center frequency) • Frequency bands where Yagi-Uda antennas are typically utilized include: HF (3-30 MHz), VHF (30-300 MHz), and UHF (300-1000 MHz)
A Yagi-Uda Antenna, commonly known simply as a Yagi antenna or Yagi, is a directional antenna system consisting of an array of a dipole and additional closely coupled parasitic elements (usually a reflector and one or more directors). The dipole in the array is driven, and another element, typically 5% longer, effectively operates as a reflector.
Basic of Yagi Antenna / Yagi-Uda Aerial - Semiconductor for You
2022年9月13日 · The Yagi antenna or aerial sometimes called the Yagi-Uda antenna is widely used for broadcast, domestic and commercial radio communications applications where gain and directivity are required from an RF antenna design.
