Hi, i have designed a project based on cavity backed helical antenna array.
Please tell me how i can find its power handling capacity. its maximum Efield = 2.1587 * e^003 V/m.
It uses strip of width 10mm and thickness 1mm as radiating element (instead of a normal wire helix).
i learnt from an IEEE paper that for a wire helix, its power handling is calculated by
(breakdown threshold of vacuum/ max. Efield)
where the paper considered the breaddown threshold of vacuum as 50MV/m.
but when i checked online many calculations involved the breakdownthreshold of air not vacuum.
i.e. 3MV/m.
Please help..
