%% Elevation Directivity of Short-Dipole Antenna Element at Two Azimuths % Specify a short-dipole antenna element having a direction along the % y-axis. Then, plot an elevation cut of the directivity at 0 and 45 degrees % azimuth. Assume the operating frequency is 500 MHz. %% % Create the antenna element. % Copyright 2015 The MathWorks, Inc. fc = 500e6; sSD = phased.ShortDipoleAntennaElement('FrequencyRange',[100,900]*1e6,... 'AxisDirection','z'); patternElevation(sSD,fc,[0 30]) %% % The plots for the two azimuth angles coincide. %% % Plot a reduced range of elevaton angles using the % |Elevation| parameter. Notice the change in scale. patternElevation(sSD,fc,[0 45],'Elevation',[-20:20])
