TransmitAntennaPattern is available as:
This example illustrates modeling transmit antenna gain. The Sender has an 8-element beamforming antenna with a steering angle applied. When you run this model, the Receiver will move around the Sender and measure the received power. It then plots the receive power on a polar plot, with the distance from the origin representing the received power, and the angle representing the angle of its position relative to the transmitter. In effect, it measures and displays the antenna gain pattern of the Sender. (See ReceiveAntennaPattern.xml as an example of modeling receiving antenna gain)
