Using MATLAB and simulink to simulate the radiation pattern of an omnidirectional antenna

Answer 1

[Chunru]

For ominidirectional response, it is a constant over directions. If you use phased array toolbox, you can plot the pattern:

antenna = phased.IsotropicAntennaElement
fc = 1e9;
pattern(antenna,fc,-180:180, 0,'CoordinateSystem','polar', ...
    'Type','powerdb','Normalize',true)
