Design of the Antenna Unit Apt to be Integrated with Air Stripline Feeding Network Structure

Air stripline feeding network is featured by low loss, high power resistance, and its amplitude and phase is easy to be controlled. So it has been extensively applied to plane array antenna designs. To integrate antenna radiation unit with air stripline feeding network will realize compact structure and high integration, as well as easy manufacture and assemble, and the cost will be reduced and the production cycle will be shorten greatly. In this paper, two types of antenna units and the simulation result are introduced, and experimental results of a kind of antenna unit and a line array consisting of the unit are given, which proves to be with excellent performance and meet practical requirements. The idea can be well extended.
