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 ...

Abstract: Partial-structure work-energy theorem (PS-WET) governing the work-energy transformation process of Yagi–Uda array antennas is derived. Partial-structure driving power as the source for ...

Abstract: In this paper, an improved five-element Yagi antenna with parasitic elements is designed based on the substructure characteristic mode theory (SSCMT). The antenna is composed of an active ...

This project focuses on designing and analyzing a Yagi-Uda antenna, a type of directional antenna that consists of multiple elements: a driven element, reflector, and director(s). The goal is to ...

LoRa gear can be great for doing radio communications in a light-weight and low-power way. However, it can also work over great distances if you have the right hardware—and the right antennas in ...
