Sorry for confusion!

Since I'm don't quite understand why shorting pin viewed as open circuited end (capacitive) will increase resonant frequency, could you please explain more detailed?

Thanks ...

Hi Sir,
Thanks a lot for your prompt response!
May I conclude the effect of shorting pin to resonant frequency as below,
1. pure inductive has lower resonant frequency since longer shorted end tran ...

Dear Sir,

Would you please advise why shorting pin of PIFA if acts inductive reactance will reduce resonant frequency and if acts capacitive reactance will increase resonant frequency?

Thanks an ...
