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 ANTENNA DESIGN BASICS - Learn More About a Yagi …
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.
Microstrip Magnetic Dipole Yagi Array Antenna With Endfire …
Abstract: A new microstrip Yagi array antenna with endfire radiation and vertical polarization is proposed. The Yagi antenna has a low profile, a wide bandwidth and a high gain. Each element of the Yagi array is based on a new microstrip antenna that has one edge opened and the other three edges shorted, working as a “magnetic dipole antenna”.
Planar microstrip Yagi array antenna - IEEE Xplore
The Yagi concept is introduced for the planar microstrip array. With parasitic director and reflector patches located on the same plane of the driven element, the beam peak, by the effect of mutual coupling, can be tilted toward the endfire direction. With this capability, the power divider and phase delay transmission lines in a conventional ...
yagiUda - Create Yagi-Uda array antenna - MATLAB - MathWorks
y = yagiUda creates a half-wavelength Yagi-Uda array antenna along the Z-axis with default property values. The default Yagi-Uda uses folded dipole as three directors, one reflector, and a folded dipole as an exciter.

Yagi-Uda antenna is the most commonly used type of antenna for TV reception over the last few decades. It is the most popular and easy-to-use type of antenna with better performance, which is famous for its high gain and directivity
Two linear eight-element arrays using a quasi-Yagi antenna have been demonstrated, one with an endfire pattern and the econd with the main beam tilted to 12s °. These arrays feature broad bandwidth and excellent radiation qualities. The endfire array has a front-to-back ratio better than 20 dB and cross polarization better than 0 15 30 45 60 ...
3D optical Yagi–Uda nanoantenna array | Nature Communications
2011年4月5日 — Here we introduce an array of three-dimensional optical Yagi–Uda antennas, fabricated using top-down fabrication techniques combined with layer-by-layer processing.
Millimeter-Wave Gain-Enhanced Yagi–Uda Antenna Array With …
The array gets a peak gain of 11.2 dBi, with measured |S11| <−10 dB from 25.0 to 27.2 GHz (8.5%). A millimeter-wave Yagi–Uda antenna comprising a third-order-mode driven dipole and a short reflector is proposed for gain enhancement.
A Yagi system has the following characteristics. 1. The three element array (reflector, active and director) is generally referred as “beam antenna” 2. It has unidirectional beam of moderate directivity with light weight, low cost and simplicity in design. 3. The band width increases between 2% when the space between elements ranges between
