%% Azimuth Directivity of Short-Dipole Antenna Element at Two Elevations % Specify a short-dipole antenna element having a direction along the % y-axis. Then, plot an azimuth cut of the directivity at 0 and 30 degrees % elevation. 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,...
