METHOD OF PREDICTING THE FAR FIELD PATTERN OF A SLOTTED PLANAR ARRAY AT EXTREME ANGLES USING PLANAR NEAR FIELD DATA |
摘要 |
The far field pattern of a slotted planar array antenna is predicted at extreme angles using an improved prediction method. The prediction method acquires planar near field data for a slotted planar array antenna and then back-transforms the planar near field data to the aperture of the antenna corresponding to X position, Y position, amplitude and phase data for the array antenna. An interpolation process calculates the excitation coefficient (phase and amplitude) of each slot element of the antenna using the back-transformed data. The excitation coefficients are then processed using an array factor program to predict the far field pattern of the antenna.
