Radiation Pattern of Half-Wave Dipole Antenna at 144 MHz

Can you please help me? I need to know the code for plotting the radiation pattern of a half-wave dipole antenna that is working at 144 Mhz frequeny

Hi Sheena,

I understand that you want to plot the radiation pattern for a half wave dipole antenna working at 144 Mhz but not able to do the same.

According to the definiton length of this dipole antenna is equal to a half-wavelength at the frequency of operation. With that we do our required calculations to find the length of the dipole antenna working at 144 Hz using where c is the speed of light.

Doing the calculations we get the Length of dipole as 1.04m.

Just make a dipole in matlab at the required frequency and change it's length to the above mentioned.

Hope it helps!

sElement1 = phased.CosineAntennaElement('CosinePower',1.5);

sElement2 = phased.CosineAntennaElement('CosinePower',1.8);

sArray = phased.HeterogeneousULA(...

'ElementSet',{sElement1,sElement2},...

'ElementIndices',[1 1 2 2 2 2 2 2 1 1 ]);

fc = 1e9;

ang = [0;0];

resp = step(sArray,fc,ang)
