Steer Subarrays of NRRectangularPanelArray
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.
getNumElements(array)
ans = 128
getNumSubarrays(array)
ans = 8
Then get the subarray positions.
getSubarrayPosition(array)
ans = 3×8
