Design data for quick development of Folded E plane Tee

Most of the microwave communication systems have requirement of power dividers that are essential for power splitting and combining operations. This paper presents a structure and methodology for designing a rectangular waveguide Folded E plane Tee. The structure proposed has the advantage of less area consumption as compared to a conventional waveguide Tee. The paper also presents design equations using which one can design a Folded E plane Tee at any desired frequency. The designs thus obtained at some random frequencies from the equations have been simulated in COMSOL Multiphysics and the scattering parameters obtained have been presented.

A multiphysics investigation of RF dry loads

Microwave absorbers/loads find applications in many microwave systems where they are utilised in testing or protection circuits. In many waveguide based systems, often lossy dielectrics are used as absorbers. Efficient thermal management of the heat generated in the dielectric is crucial for the functioning of the load. As such the design of a load is a multiphysics problem involving RF, thermal and in some cases fluid flow analysis. In this paper, different structures of low power loads are analysed for their RF and thermal characteristics and behaviour. These loads are designed for 3.7 GHz and simulated in COMSOL Multiphysics.
