These highly directional antennas have a driven element and a number ... and to learn why it’s more properly known as the Yagi-Uda antenna, ... but the radiation pattern is almost equally ...

But omnidirectional antennas like the halo are rarely used for that; Yagi-Uda antennas are the norm. A Yagi-Uda can also be used for vertical polarization if a directional pattern is desired, but ...

A Yagi–Uda directional antenna — the work horse of radiofrequency communications for more than 60 years — has now been demonstrated at visible wavelengths.

The demonstration of a Yagi–Uda nano-antenna that operates at visible wavelengths gives hope for a convenient means of directing radiation patterns from nanoscale light sources such as single ...

Products on show will include the JAVA broadband log periodic FM Antenna for high gain directional applications and low VSWR across the FM band. The companies will also place focus on the J3YF 3 ...
