Hello what is the difference between wave port and lumped port in HFSS. upenn. Hi, I am new to the HFSS software. Nov 23, 2013 #1 V. One way to do this is to create two ports (lumped port, wave . The proper creation and use of the Continue reading Intro to Ansys HFSS Port Types — Lesson 1 本文大纲本文章分三部分：（一）wave port与lumped port的理解（二）两种port的仿真操作用法（三）S参数归一化的问题说明：这里说的port主要是针对Ansys的HFSS HFSS PORT 终极解决方案（三） ,EDA365电子论坛网 As per HFSS manual size of port is 8hx10w but then also incident power is to lowered to few mW. Activity points 1,361 hi im a beginner at hfss. I want a parallel R and C (value R_load With Ansys HFSS, your port type choice for various applications is almost a matter of religious conviction. core. Is used to determine the initial maximum tetrahedra size and is the frequency at which HFSS solves the given model. 6GHz. com I am using the HFSS and I would like to know how to set the port. S. Awaiting your replies, Regards . Then use a circuit simulator to de-embed the response of the lumped port. The antenna gives expected results using lumped port, i tried using coaxial port but was unable to achieve the same results. Thi Does anyone have an idea about the wave port or lumped port in hfss ,which should be used especially for microstrip patch antenna in uwb range i. 2. General advice will be provided for initial port sizing, followed by diagnostic procedures to use to evaluate whether or not a user Lumped ports are similar to traditional wave ports, but can be located internally and have a complex user-defined impedance. Lumped Ports in IE3D 1. I do not have the below steps (check the attached image) as those existing in the HFSS V10 User Guide> I am using HFSS v13. This lesson details the key points for defining these ports along with their differences and uses. Therefore you need the vias crossing the port and shorting the grounds (now you're back with two nets in the port and a CPW excitation). wave port hfss For lump port excitation, you need to draw a strip to merge the two grounds and signal line together. in this way you can built a waveport to lumped port stripline Yes, use the wave port unless your frequency is pretty low. The waveport first mode may not be the CPW mode. H. 위의 구조를 제외한 모든 구조에 사용됨 <Solution Type> 솔루션 타입 Lumped port and Wave-port 2. Thread starter m_uzman; Start date Aug 26, 2006; Status Not open for further replies. The enclosed current is determined by the line integral of H around the periphery of the wave port (as it is a PEC boundary) so no integration line is required. I am designing a microstrip patch antenna using Ansys HFSS. Joined Jun 13, 2012 Messages 1,476 Helped 407 Reputation 818 Reaction score 385 Trophy points 1,363 Location hfss . 6. Lecture LE03: Wave and Lumped Ports; Workshop 3. 001 Ohm Lumped port setup: i used PEC sheets connect two ground traces to the ground plane PEC. What is the reason? Theory? What is the optimal wave port size? Regards, H. Lumped Port Selection This presentation is one in a series of Port Tutorials, intended to help users better Wave port setup: the wave port touches 1 signal terminal and 2 ground terminals, for ground, set terminal renormalization to 0. ldi. No de-embedding. 4. I plot S11 and found out that the most voltage is Does anyone have an idea about the wave port or lumped port in hfss ,which should be used especially for microstrip patch antenna in uwb range i. the distance from the antenna patch plane to top face of the box should be lamda/10. HFSS Port Selection Example: Ports inside Model Volume, part 1 Microstrip Port on RF Board Some of these excitations offered by Ansys HFSS are wave port, lumped port, and Floquet port. Thanks for referencing those courses - unfortunately the antenna simulation still does not match what is expected. Can anyone help wme with the waveguide port excitation in HFSS 2024 R2, I cant even find the option for waveguide right now!!!its urgent . com Antenna/filter, power combiner/divider, couplerMetamaterial , Multi-layer Incident wave is setup in excitations (right click to assign, then go to incident wave and you can select several different types). For microstrip, you would make a rectangle from the upper conducter line to the the ground and insert an integration line from bottom to top. HFSS Port Selection Example: Ports inside Model Volume, part 1 Microstrip Port on RF Board Dear Sir or Madam,nI have an HFSS model with 2 waveports (In, Out) and 2 Lumped RLC elements. costox Full Member level 4.
