Farfield directivity
WebFarfield data output provided by CST MWS is related to spherical coordinates Theta and Phi. Many times farfield data for different polarization directions is required. The macro … WebThe farfield directivity function is then derived from the autocorrelation function of velocity at the aperture. The beam pattern is verified experimentally, and comparisons of the diffraction patterns caused by coherent and "incoher- ent" beams are shown. Finally, applications where use of the

The directivity analysis group is a natural extension of the Projections from a monitor box analysis group in which surface equivalence is once again invoked to determine the far fields radiated outside of a closed box from the radiating sources (Es , Hs) located inside the box, as depicted in the above figure. These … See more Illustration of a set of monitors above an infinite ground plane and their virtual images. In many instances, it is appropriate to consider the antenna as mounted on top of a … See more After inserting the directivity analysis group, a set of monitors forming a box will be inserted into the simulation domain. In the Setup Tab of the … See more In Projections from a monitor box , the far-field patterns are found for two dipoles surrounded by the box monitors. Here, we use the directivity … See more WebIn addition to this, due to the recent interest of the modern age in monitoring the directivity of the field’s radiated by nano-antenna structures, a specific design is required for …
WebFarfield Plot – Plot Mode ... (Directivity, Gain, Realized Gain) sets the Color Ramp such that 0dBi is always in the center of the Color Ramp. Calculation settings frame. Reference distance: Set the radius of the virtual sphere for which the farfield is calculated. Available for plot modes e-field / h-field and power pattern. In a normally-operating antenna, positive and negative charges have no way of leaving the metal surface, and are separated from each other by the excitation "signal" voltage (a transmitter or other EM exciting potential). This generates an oscillating (or reversing) electrical dipole, which affects both the near field and the far field.
