    %% Vertical and Horizontal Responses of Crossed-Dipole Antenna
% This example shows how to create a crossed-dipole antenna
% operating between 100 and 900 MHz and then how to plot its vertical
% polarization response at 250 MHz in the form of a 3-D polar plot.

scd = phased.CrossedDipoleAntennaElement(...
    'FrequencyRange',[100 900]*1e6);
plotResponse(scd,250e6,'Format','Polar',...
    'RespCut','3D','Polarization','V');

%%
% The antenna pattern of the vertical-polarization component is almost
% isotropic and has a maximum at $0^{\circ}$ elevation and $0^{\circ}$
% azimuth, as shown in the figure above.
%
% Plot the antenna's horizontal polarization response. The
% pattern of the horizontal polarization response also has
% a maximum at $0^{\circ}$ elevation and $0^{\circ}$
% azimuth but no response at $\pm90^{\circ}$ azimuth.
