Below is my understanding of photoelectric effect, please correct me if I am wrong.
It is an quantum electronic effect in which matter emits electrons after receiving energy in the form of EM waves. E.g. imparting X-rays on matter.
So if we impart a high frequecncy wave (say f1) on a metal body (same thing that happens to antenna), it would emitt electrons?
Here I assume that f1 is far greater than threshold frequency required to make electron escape from crystalline structure.
Then why doesn't my cell phone antenna emitt electrons...

There could be only one reason that cell phone frequency is well below threshold frequency...Because even with lowest possible intensity (only one photon at a time), frequency which is above threshold would make atleast one electron escape.
Please correct if I am wrong, thanks in anticipation.
