I am designing a multi band antenna and i use ADS to simulate it, i have some warning message when it simulating the S-parameters:
inaccuate (high frequency ) calibration;
electrically large via using lumped model;
higher order modes at the ports;
grouped strip-slot ports;
mesh density is too coarse;
can anyone tell me why did this happen??
thanks!!!
