How do I calculate antenna efficiency?
The graph gives GAIN (peak Directivity) ,but what is my Directivity?
who can i get efficiency (GAIN/Directivity)
my code:
C = 3*10^8;
F = 10*10^6; %hz
Z0 = 73 ;
Lamda =C/F; %m
ant_short = dipole('Length', Lamda/10 );
ant_Half = dipole('Length', Lamda/2 );
ant_full_wave = dipole('Length', Lamda);
ant_one_and_half_lamda = dipole('Length', Lamda*1.5);
Antenna=ant_Half
pattern(Antenna, F, 0, 0:1:360);
my fig:
