I need to load the antenna with "Wu-king" profile, that is to load the antenna at an equal intervals such that the resistance per unit length varies as a particular funtion of the position along the antenna. I want to not only load it at the port.

I tried it, but a problem appeared that the antenna always have an input impedance with capacitive reactance. Whereas before loading, the input impedance have capacitive reactance before a frequency point and inductive reactance after that frequency. I think it maybe cause by cutting the antenna, for the cut will always brings capacity, so I enlarge the cutted part, that is to say, enlarge the distance between the cut so as to bring a smaller capacity, but it didn't change much.
@elomatic
Can you upload some examples using CST MWS, e.g. resistively loaded antennas and capacitively loaded antennas?
To all:
Thanks for helps from all of you.
