Yagi antenna can be used at transmission or reception but are more used for transmitters. This antenna is a directional system consisting of an array of a dipole and a reflector and one or more ...

I've constructed hundreds of antennae in the past. Bowtie dipole arrays, biquads, parabolic reflector dipoles, straight up yagi, logarithmic yagi, log periodic, heliacal and simple 1/4 whips.

Yagi and Uda combined these principles to create a multi-element antenna design that demonstrates strong coherent interference in a particular direction, thus boosting transmission or detection.

In this paper, we present a design of the Yagi-Uda antenna, which can be switched to achieve radiation patterns toward different angles with a step of 45 degree. The antenna covers the ISM band for ...

A quasi-yagi antenna Ka-band frequency range has been proposed and simulated. It consists of three directors, a driver, a stripline feed, a substrate and a ground plane. Optimasion is obtained by ...
