Abstract
A three-dimensional (3D) antenna array system in the form of a phased array antenna having a first antenna array and a second antenna array, a calibration circuit including an external signal generator, and a hinged power transformer is described. The external signal generator is electrically connected to the first antenna array, and the first antenna array is electrically coupled to the second antenna array via the hinged power transformer. The hinged power transformer mechanically joins the first antenna array to the second antenna array in one of a first position and a second position, with the first antenna array being disposed at an angle in relation to the second antenna array when the hinged power transformer is disposed in the first position.
