// given data
f = 300*10^6; // operating frequency in Hz
c = 3*10^10; // velocity of EM wave in cm/s
// Calculations
lamda = c/f; // wavelength in cm
// Physical length of antenna is made 5% shorter than desired length as per rule of thumb
l = lamda/2; // length of halfwave dipole
lphy = l-(5/100)*l; // as per rule of thumb
// Output
mprintf('Length of a half wave dipole to be cut = %3.1f cm',lphy);
