摘要
Abstract
An antenna with frequency-phase scanning array is studied.This array antenna is composed of a fed net with an air stripline structure and a wide-band unit antenna, and it can realize the frequency scanning characteristic in one dimension and the phase scanning characteristic in the other dimension.Through simulation and optimization, the related size is confirmed, and the antenna is manufactured and tested.The test result indicates that: the loss of the fed net with air strip line structure is relative small;the relative bandwidth of this antenna reaches 14.7% (wide-band antenna in the radar field);the scanning angle is bigger than 60°;and in the range of the whole band, the side lobe lever is better than-18.5 dB.关键词
