antenna efficiency

I've tried HFSS ver.10 and it's efficiency simulation is way off the measurement from chamber...
any other candidates?
 

hi electro, that has to depend on what type of antenna you are simulating. HFSS is a full wave simulator using FEM, this should give you a much accurate result. But that has to depend on how you model you antenna in the simulator. But then, with any simulator, you can only get a rough idea of the actually efficiency so its best to build one and measure to find the actual efficiency of the antenna you have designed. Good luck
