Far-field radiation
WebThe radiation takes the measurement in far field which lessens the pattern should be deterministic theoretically when the interference caused by the measure antenna (MA). The samples of the field are chosen to fulfill the Nyquist limit sparse measurement is determined by the characteristics [6]. WebFar Field or Fraunhofer Region. The far field region is the most important, as this determines the antenna's radiation pattern. Since antennas are used to communicate wirelessly from long distances, this is the region of …
