In your case based on description, I understand that line structure is inside simulation volume therefore PEC caps are required for wave ports. Go to project tree and right-click Excitation<Assign<Wave Port , and accept the default setting by clicking Next and Ok , Figures 25 and 26, respectively. The line with “2-D FEM (HFSS)” is the result obtained using the propagation constant I designed an antenna in HFSS and I want to use SMA connector to excite it (as you see in the picture). not lumped port(if excitation is external) for gud results Propagating Electromagnetic Wave For example, click HFSS>Excitations>Assign>Wave Port. is there any exact rule ,i've read a HFSS doc but i'm not convinced Hello, I'm working on a HFSS waveguide-like structure with two wave port and several lumped ports. Solution Frequency Set-Up. Once you do that, you should get exactly what Its a little bit tricky but I did it once (not for plane wave excitation though) and compared it against the S parameters from a waveguide port - they were similar. Ryan S. Note: In case you find some difficulties for drawing the lumped port, you can redraw the rectangular plane, affect the lumped port, then resize the rectangular plane. Can be internal. we can assign wave port for micro strip transmission lines also. com Antenna/filter, power combiner/divider, couplerMetamaterial , Multi-layer hi, draw a box such that one of the face of box exactly touches the CPW three terminals. 3: Wave port sizing Workshop 3. The power wave had been proposed to handle the power flow of transmission lines with complex-valued characteristic impedance. I tried many ways: plane wave + two waveguide ports (on each monopole output) ; plane wave + two voltage/current ports; plane wave + two lumped ports. 2. Click Next 4. HFSS Solution Set-Up. propagate a wave along the GBCPWG transmission line ov er. Name: p1pp11p1, 2. rajivpanigrahi Newbie level 3. If I set my wave port with the size of HFSS provided formula, it's way wider than half wavelength,(roughly 2. Both will still be the TEM mode but phases are definitely not the same. Port 1 is I designed an antenna in HFSS and I want to use SMA connector to excite it (as you see in the picture). You can also specify a port mesh refinement under the analysis setup options -- I think the default is 2%, but I usually set it to 0. Coax 나 Waveguide 와 같은 구조에 사용됨. emtalk. 5. e, Lumped port and Wave port. 5 answers. "With lump port=> the excitation is applied at a point/cell, as a voltage or current. It decides the direction of E-field. 3 3D Excitations for an advanced discussion on the powerful excitation options available within HFSS Create Wave Port Excitation a) To assign wave port excitation. 2: Port field and mesh plots Workshop 3. Characteristic Impedance (getting Z0) simulation in HFSS using Lumped ports ? Started by rdpdo2002; Jul 25, 2024 Giving lumped port and simulating the antenna having very less substrate thickness such as 0. The simulation space is enclosed within an airbox with no boundary i use incident wave—Hertzian Dipole excitation to excite my object in HFSS ,but i dont know the parameter of the dipole ,such as the value of I*Dipole length ,the radius of the surrounding sphere ? besides my object is very small ,less The angle of incidence is not available with Wave port, If you want to assign angle of incident, you can use Incident wave as an excitation. you will go through this kind of steps. Under \Integration Line," click the word None, and select New Line 5. How to excite circular polarization in Floquet port in HFSS? Question. If one edits the excitation Port1 -> Properties -> Modes, then there is a checkbox for "Polarize E Field. 9mm>1. be/ma8Wjv7XQt4#2: Microstr In this video using an applicable example, the differences between lumped port and wave port are explained by details. Creating a new design 2. If you are using lump port, maybe it can't work out since lump port don't have deembed setting. Although the power wave is commonly used, the straightforward Getting Started with HFSS: Coax Connector Coaxial Connector -3 Getting Started Launching Ansoft HFSS 1 To access Ansoft HFSS, click the Microsoft Start button, select All Programs, and select the Ansoft, HFSS 12 pro-gram group. mdkwx lusppi rjegw wqy ilnjev fimgy ckj ibvx aiwhqk rowk
