N = getNumSubarrays(array)
returns the total number of subarrays, N, in the panel
array when the EnablePanelSubarray property is
set to true. N is returned as 0 when the
EnablePanelSubarray property is set to false.
Construct a 5G antenna array with panels on a 2-by-2 grid with each panel being a 4-by-4 array. Each antenna element consists of two short-dipole elements. Use each panel as a subarray. The elements are spaced 1/2 wavelength apart and the panels are spaced at 5/2 wavelengths. Plot the response of the array at 6 GHz. Assume the weights for each element within the subarray is unity.
c = physconst('LightSpeed');
fc = 6e9;
lambda = c/fc;
ant = phased.ShortDipoleAntennaElement;
array = phased.NRRectangularPanelArray(ElementSet={ant,ant}, ...
Size=[4, 4, 2, 2], ...
Spacing=[0.5*lambda,0.5*lambda,5*0.5*lambda,5*0.5*lambda], ...
EnablePanelSubarray=true,SubarraySteering='Custom');
Display the array pattern.
pattern(array,fc,'ElementWeights',ones(16,8));
Compute the number of elements and the number of subarrays.
N — Number of subarrays in panel array nonnegative integer
Number of subarrays in panel array, returned as a nonnegative integer. Number of
subarrays in the panel array when the
EnablePanelSubarray property is set to true.
N is returned as 0 when the
EnablePanelSubarray property is set to false.
