%% 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. % Copyright 2015 The MathWorks, Inc. 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. scd = phased.CrossedDipoleAntennaElement(... 'FrequencyRange',[100 900]*1e6); plotResponse(scd,250e6,'Format','Polar',... 'RespCut','3D','Polarization','H');
