Viewing 7 reply threads. b) Dimensions of the SiC DUT CPW. For these two cases, the dimension of the port is computed automatically by analyzing the geometry. Course Overview. There are seven types of excitations: wave-ports, lumped-ports, floquet-ports, incident fields, voltage and current sources and magnetic bias sources. The Current Source dialog box appears. 1 to 10. same TE/TM modes) so these two will have the same matching condition. T. It sounds like the layout oriented editor (when you mentioned the z position on the entire board can only have one material assignment) would not be able to have conformal layers where the Z position at different X and Y locations are different materials. Continue boundaries = hfss. Name of the primitive to create the edge port on. 74/0. 1mm or lesser is difficult to simulate. TYPES OF APERTURE ANTENNAS 2. This port type is very useful for exciting microstrip, stripline, coaxial, or waveguide transmission lines. But the lumped port will not give the impedance result, and I have to provide impedance for the S-parameter results. Joined Mar 5, 2024 I dont know about all port types but I always use two conductors to excite the model. I used 5 to 10 times the height of the substrate 100um and the port was too narrow for very thin line widths.

It sounds like your line is not (impedance) matched to the port. You can assign a • HFSS assumes that each port you define is connected to a semi-infinitely long waveguide that has the same cross section as the Wave Port. I want to simulte CPW ,and I expect the structure of CPW give the standard impedance 50 Ohm. Usually what I do in such cases is integrate the lumped port into the ground plane. Jul 16, 2007 #8 B. This document provides an overview of lumped ports and wave ports in ANSYS HFSS. I studied online help and ANSYS HFSS user guide and understood that in a Modal solution, the S-parameters are determined by employing the concept of the incident, reflected and transmitted power whereas in Terminal solution the voltages and Ansys HFSS Port Types Practice Quiz Course Assessment — Ansys HFSS Port Types Time limit: 0 Quiz Summary 0 of 10 Questions completed Questions: Information You have already completed the quiz before. My interest is only with bringing my layouts into the solid modeler. A wave port represents the region through which electromagnetic energy enters or exits the solution space. Ususally in driven terminal mode, an TEM mode is assumed: here more modes are exisiting, means more than two conductors are touching the wave port surface / lumped port sheet or too less terminal are defined --> switch to driven modal and redefine the ports Yes, you will want to define a port at each end of the conductor - the ports will be defined between conductor and ground. 1. 5V incident voltage which equals to 1V of source in experiment ). tmiilucsvhxlqreeuzaqudoebqgucxdkdafdomrzupzyx
