A new power divider architecture for suspended strip line

Abstract

In this paper the authors present a novel power divider architecture intended to be used with the Suspended Strip Line (SSL) transmission line. The new antenna array systems, that are designed to work in the millimetre wave ranges, are suffering from the losses in their beam forming networks. In order to mitigate the losses one can use special types of transmission lines. One of them is the so-called Suspended Strip Line (SSL). In this paper the authors present a novel RF power divider intended to be used with the SSL. It uses the properties of the suspended stripline geometry in order to give the designer an increased number of degrees of freedom to achieve the desired power division ratio and a good input match. The advantages of the proposed geometry are compactness, good power handling, no need of any soldering or introducing lumped elements and the sole use of standard 50Ω lines.

Low Loss High Power Air Suspended Stripline Power Divider for High Power Division Sub-Systems Applications

“…One of the solutions of this problem is using suspended stripline (SSL) [19]. In the (SSL) the center conductor is printed on a substrate which is suspended between two parallel ground plates which reduce the losses compared to microstrip configuration [20]. SSL configuration is used to support the high power due to its low insertion loss and high-power handling capability.…”
