碩士 === 國立臺灣大學 === 電信工程學研究所 === 106 === This thesis presents a pattern calibration methodology to suppress the multipath signals encountered in the measurement of two-dimensional (2-D) antenna far-field patterns in a hybrid antenna measurement facility. Instead of using the field data measured at various frequencies or many locations to create diversities, this methodology has a unique advantage of calibrating the radiation pattern by using the measured data at a single frequency. The proposed calibration methodology is based on the application of matrix pencil method (MPM) to extract characteristics of multi-path interference signals by measuring a reference antenna, and results in a calibration factors matrix. The radiation of antenna under test (AUT) is then recovered from the measurement by incorporating this calibration factors matrix without the need to perform multiple measurements over AUT. Examples of simulation and measurement are presented to demonstrate the feasibility and utilization of this calibration methodology.
