Information about detuning of antennas

[naumanhbk]

hello,

plz tell me about detuning of antenna and how it can occur. ??
i think when antenna came into contact with the radiation from another metal it detunes in some cases or
in devices where different components are integrated with antenna, currents induce on them or on the ground plane, which causes detuning...
plz tell me if there is some reality in these theories...

thanx

Re: detuning of antennas

When you say "came in contact" are implying the antenna changed its physical properties?

Unless whatever it came into contact with was acid, heat or something which caused the trace to *****, this is impossible simply by RF radiation.

Adding battery holders or a case is something more realistic that could have changed.
