Model antenna accounting for incident power wave (RX) and radiated power wave (TX)
RF Blockset / Circuit Envelope / Elements
Model an antenna using the Antenna block:
Convert a Simulink® input of an incident power wave vector into an RF Blockset™ voltage at the antenna ports.
Convert current at an RF Blockset antenna port to a Simulink output of a radiated power wave vector.
Introduce antenna impedance into an RF system.
By default, the antenna block is an isotropic radiator producing a Simulink output signal. For an isotropic radiator, specify the gain and impedance of the antenna in the block parameters. The Radiated carrier frequencies parameter is a set of carrier frequencies over-which the Antenna block creates the radiated power wave. For more information, see Radiated Wave and Incident Wave.
