Hi,

How to get Total Radiated Power for an Micro-strip antenna in FEKO?. Antenna is excited by 1V source. In PostFEKO, Cartesian plot -->Power  gives Active Power  &  Loss Power.     Is Active power is Total Radiated power ?

    You can get the radiated power by requesting a 3D far field. 

    Then it will be given as an option to plot on a graph under the far field results in POSTFEKO:

    Or you can read it from the ASCII *.out file:

    Integration of the normal component of the Poynting vector in the angular

    grid DTHETA = 5.00 deg. and DPHI = 5.00 deg. (2701 sample points)

    angular range THETA angular range PHI radiated power

    -2.50 .. 182.50 deg. -2.50 .. 362.50 deg. 3.51049E-03 Watt

    0.00 .. 180.00 deg. 0.00 .. 360.00 deg. 3.46344E-03 Watt

     

    By the way, if you want to have a set radiated power, e.g. 1 Watt, you can set this in CADFEKO under Power settings, e.g
