  S-Parameters for Antennas (S11, S12, ...)
  
  S-parameters for an antenna are introduced. S11 is known as the return loss, or how much power is reflected from the transmitter to an antenna. S21 or S12 represents power coupled from one port to another, a useful parameter for determining coupled power
