3D Antenna Patterns

3D patterns can be defined in any coordinate system. Spherical coordinate systems are most commonly used to define antenna patterns.

Figure 1 shows the coordinate system used in WinProp for the 3D display of antenna patterns. The main direction of radiation is ϑ = 0° and φ = 0°.

Figure 2 to Figure 4 show the 3D pattern as well as the vertical and horizontal plane of a Kathrein K739856 antenna together with the coordinate systems used for display in AMan.
