Abstract
Technologies directed to calculating an array factor for a phased array antenna are described. One wireless device with a phased array antenna receives inputs and defines a first variable in a first coordinate space and defines a set of amplitudes of a one-dimensional or two-dimensional inverse Fast Fourier Transform (IFFT). Each amplitude is based on the third value, an excitation amplitude and an excitation phase or delay of a respective antenna element. The wireless device determines first array factor values in the first coordinate space by computing the one-dimensional IFFT using the first variable. The wireless device performs a spline or linear interpolation to obtain second array factors at points in the physical coordinate space. The wireless device sends the second array factors to digital beam forming (DBF) circuitry that causes the phased array antenna to steer a radiation beam using the second array factor values.
