    In this work, we present a theoretical analysis of wireless optical nanolinks formed by plasmonic nanoantennas, where the antennas considered are Yagi-Uda and cylindrical nanodipoles made of Au. The numerical analysis is performed by the finite element method and linear method of moments, where the transmission power and the near electric field are investigated and optimized for three   common type of antennas is Yagi-Uda antenna uses this principle. It can be seen in most households to receive UHF and VHF TV signals. Yagi-Uda antenna uses the principle of radiation coupling, in which the feeding is to one element and other elements will be activated by it. Microwave Antennas 1. Parabolic

    Antennas, in essence, channel electrical power into electromagnetic signals. The shape, size, and connectorization all affect the antenna radiation pattern. Two key parameters in assessing the performance of an antenna are directivity and gain―directivity is a measurement of the concentration radiation in a direction while gain represents the The number of antennas in the United States was on the order of one per household, representing growth rivaling the auto industry during the same period. By the early 21st century, thanks in large part to mobile phones, the average person now carries one or more antennas on them wherever they go (cell phones can have multiple antennas, if GPS

      In radio, an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts (radio).   is necessary to make the phased array use­ ful for electromagnetic susceptibility testing.

Abstract: In electromagnetic-susceptibility testing of electronic equipment, the ideal incident field is a plane wave. To approximate this condition, a seven-element array of Yagi-Uda antennas has been constructed and tested at a frequency of MHz.

The element weightings are determined by a near-field synthesis technique, which optimizes the uniformity of the field throughout a rectangular Get this from a library.
