Electrical Performance of Air Core Copper Rectangular Coaxial Line Based Devices
Keywords: finite element, s parameters, full wave
A novel Poly-Strata fabrication process employed by Rohm and Hass in Blackburg, VA allows the manufacture of 3D mm waveguide circuits. The resulting 3 Dimensional Micro Electromagnetic Radio Frequency Systems (3D-MERFS), deliver higher performance than planar waveguides. A typical cross section of devices fabricated in this manner is shown below: The process can be used to produce many different kinds of passive circuits, such as the hybrid coupler shown here: Another device is a folded hybrid coupler: ANSYS is a general purpose finite element program that includes a full wave frequency domain electromagnetic solver. We intend to calculate the s parameter performance of one of these devices and compare with known measured data as a way to validate results achievable with ANSYS.
