Abstract
The present disclosure relates to manufacture of an active array antenna from a combination of modular sub-arrays, nominally of equal size; each sub-array being associated with a separate receiver and/or transmitter. A solution to calibrating a modular array is the inclusion of a calibration manifold having multiple 1st ports that connect to respective sub-arrays between their passive network and their respective receiver and/or transmitter. Each of the first ports communicate with a common second port through which a signal can be introduced in order to be received at each element of each sub array, or through which a signal from any element of any sub-array can be received. This allows any element of the sub array to be calibrated at any time including during operation.
