Cst directivity
WebFDTD. This page describes how to calculate the directivity of an antenna, defined by IEEE as the ratio of the radiation intensity in a given direction from the antenna to the radiation … WebHome: Macros > Macros > Farfield / Slant Polarization. Farfield 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 projects the global farfield data such as directivity (theta,phi) onto user given polarization planes along a path.

WebAn Antenna radiates power, but the direction in which it radiates matters much. The antenna, whose performance is being observed, is termed as subject antenna. Its radiation intensity is focused in a particular direction, while it is transmitting or receiving. Hence, the antenna is said to have its directivity in that particular direction.
