1. c = velocity of light in a vacuum ( 3 x 10^8 ) , me too, i got wavelength = 333mm , then i gave 5 coils, all parameter i put to superNEC simulation, but the result made me unsatisfied.
2. I make a helical antenna for jammer GSM, then, I applied to a device that has a voltage of...
i have some question :
1. i have pameters, i got from the formulas λ = C/f , D = C/π , α = arctan S/C , L = C/cos〖α 〗 , G = k 12 Cλ2 n Sλ , long axis = n x S , then i simulate with supernec , i got the gain -2dB , and radiation pattern there's much back lobe. Is there somethin wrong with...
