Abstract

A novel phase array antenna with integrated couple line is designed and measured in this paper. This kind of structure assures the stability of monitor system in active phased array radar system. The relative frequency band of the phased antenna array antenna is larger than 25% and it can electrical scan 60 degree both in E-plane and H-plane. The couple coefficient between the ports of different antenna elements in 8-ele structure and the couple port of couple line are in good consistence. Curve of the couple coefficient in the whole frequency band is flat.
