We sometimes hear amateurs telling that an antenna made of element shorter than a full wavelength do not perform well. It is a fact that reducing the size of elements by 50% does lower the efficiency ...

Gain: it is the amount of energy radiated by the main lobe compared to the energy radiated by an isotropic antenna. The larger the aperture ... with no sidelobes. Example for a 6 dBi Yagi (a power ...

This copper-foil Yagi antenna might not do everything, but it really seems to tick off the boxes for gain and directionality along with ultra-portability. [Ben]’s field test results were most ...

In this work, a high-gain broadband printed Yagi directional antenna for applications in ISM bands (686 and 915 MHz) is presented. The proposed antenna was designed to be implemented in a wireless ...

This copper-foil Yagi antenna might not do everything, but it really seems to tick off the boxes for gain and directionality along with ultra-portability. [Ben]’s field test results were most ...

A Yagi antenna with 7 elements, containing a driver, a reflector and 5 directors, were considered in this project, and the center frequency is 435MHz. 本项目拟设计一款7单元八木天线，包含1个主振子，1个反射器，5个引向器，中心频率 ...

The SENCITY® SPOT-M is a WiFi Yagi Antenna specifically designed for CBTC (Communication-Based Train Control) applications. It operates in the 2400-2485 MHz frequency range and features 14 dBi gain, ...

Here is presented a model of 4 elements fullsize yagi antenna for 20m band. The model is optimized for the boomlength of 7.5 meters while keep maintain good VSWR < 1:1.2 throughout 20m band, gain, and ...

The microstrip branches then transmit the energy to quasi-Yagi antennas for radiation. Using quasi-Yagi antenna array to enhance the gain makes LWA attractive in mm-Wave applications. Because of the ...
