Abstract
In order to solve the problem of sidelobe error caused by probe pattern in current antenna planar near-field and far-field transformation, a new near-field and far-field transform algorithm with probe compensation is studied by combining the advantages of traditional pattern development and edge current approximation method. By measuring the array antenna in a microwave anechoic chamber, the traditional mode expansion method is compared with the hybrid algorithm. The results show that the measurement accuracy of this method is 1.445dB higher than that of the traditional method, and the calculation efficiency is significantly improved, which proves the effectiveness and engineering practicability of this method.
