How do I model a directional radio antenna?

An antenna pattern is oriented around Phi and Theta angle values. If you are unfamiliar with the use of these values, then refer to the Creating a Wireless Network tutorial or to the Wireless Module User Guide in the product documentation. A good explanation for Phi and Theta is given in the Wireless Module User Guide in chapter 3 Advanced Wireless Modeling. This chapter has a section called Wireless Objects in the Node Domain where the Antenna Module is described.An antenna module in a node has attributes for a Pointing Reference Phi and Theta. These specify the reference direction for the antenna pattern used by the antenna. The reference points to the point of maximum gain of the antenna pattern. Thus, the antenna pattern's Phi and Theta values orient themselves around the reference Phi and Theta values of the antenna module.This reference point can then be pointed to a specific latitude, longitude, and altitude. These are specified by the target latitude, target longitude, and target altitude attributes of the antenna module.The target latitude and logitude must be specified in degress while the target altitude must be specified in meters.
