Just according topersonal expericence, For your reference,
In US or Europe,antenn engineerswill build the model and simulation in software(like CST HFSS etc)before build mockup, once the simulation result is positive and then they build the physical mockup to verify the simulation result,normally the results are similar compare to the simulation,but in china,antenna engineers always said the software just waste the time and useless; and most of engineer's simulation result very different with mockup; so the question is :
1.if the software is useless, why all of the foreign engineers use it? meanwhile the software license is very expensive.
2.why foreign engineers can get the very close result between simulation and mockup,but most of us can't?
Obviously,the answer is not eay,but i believe all of the foreign use the software so the software is not useless,opposite,the software is very helpful for antenna engineer,but you need to know how to use it and how to handle it, that's mean youneed to know the principle of the software,how isthe software work? and then once you get the simulation result, you can judge the result is right or wrong,further more analysis the difference; the conclusion is if you can master the software,you can save lots of money in your company, beacuse you don't need to build mockup which maybe get the bad result;
I believe all of us are very familiar with the PIFA, Monopole ,IFA, FICA, Loop.dipole etc traditional antenna type, and you can get the good passive(s11) and active performance in your projects;but think over it, do you know how these anntena type work? what's the princriple of these antennas type ? what's the different?
The principle of the transmission line,simith chart, how much you know about it?if give you the load impedance and the tranmission line characteristic impedance and the operation frequency, can you calculate the any point impedance of this transmission line? what's the formula?
The last thing is innovaion,that's we lack of it;
all of these stuff is alsoneed i to figure out,we need to keep learning, and then we have chance to close to sucessful;
Best Wishes all of you;

有无后续呢，中式英语？
不是不想用啊，是没有太多时间仿啊，评估国内项目一两天给报告，仿真的时间太长
