ABSTRACT:
Twin lead transmission lines are positioned in close coupling relationship o linearly polarized and planar arrays of antenna radiating elements to provide a self contained instantaneous antenna test and measurement system. Near field energy from the transmission lines is coupled to the transversely arranged antenna dipole elements to permit testing without degrading antenna performance. Signals induced on the radiating elements are of uniform amplitude and linearly changing phase equivalent to those of a far field plane wave. Various tests such as antenna failure and performance characteristic measurements, including gain, pattern and phase difference, can be made automatically. A balanced power divider distributes RF power equally to the twin lead transmission lines and a system processor controls phase shifter scanning elements and analyzes the various output parameters to provide the desired test and measurement information concerning the selected array of dipoles and components.
