Technical Workshops

COMSOL EM Simulation Workshop


If you are in the process of designing or characterizing an antenna and want to find out how you can model its properties, this workshop is for you. The COMSOL Multiphysics® simulation platform together with the add-on RF Module offers functionality for simulating antennas of all types and sizes, and for any range of frequencies. Using the software, you can calculate performance indicators such as impedance, directivity, far-field radiation pattern, efficiency, gain, VSWR, and S-parameters.

During the workshop, we will cover simulations of antennas in arrays, interaction with radomes and reflectors, and wireless power transfer. The presentation will include a demo of a double-ridged horn antenna and time for questions. The workshop will last for 1 hour and 40 minutes.

Cadence EM Design and Analysis Workshop


Advanced Antenna Design and Integration Through Circuit/EM Co-Simulation (50 minutes)
This presentation explores recent developments in mmWave technology from the perspective of EM simulation, in situ circuit simulation, phased-array synthesis, and RF PCB design. It will discuss system requirements that drive antenna/front-end architectural decisions for mmWave applications, antenna optimization, and array configuration and generation. It will also present the use of RF system design software for link budget analysis. In addition to antenna/antenna array design and simulation considerations, this talk will examine the integration of the array with front-end beam steering electronics through RF routing and its simulation with front-end circuitry and feed network before transferring to the PCB layout editor.

Attendees will learn how best-in-class RF design, manufacturing, and EM system signoff combine to support PCB-based array development and integration with the IC through the PCB system level from within a comprehensive front-to-back workflow from Cadence. Multiple design examples will be presented.

Use of EM Field Solver to Simulate 50GHz PCB on Correlation to Measurements (50 minutes)
This presentation explores the influence of the field solver numerical solution space on measurement correlation for PCB applications. The underlying challenge is that for EM simulation, we are almost always forced to simulate only a small subset of what is being measured, and thus we are forced to introduce artificial field boundaries into the numerical modeling. Potentially, this can cause miscorrelation of the structures being characterized and neglect system-wide coupling effects from other signals, the power delivery, and EMI effects. As system speeds increase, these effects must be considered and quantified.

To examine this topic, an IEEE P370-compliant test platform will be used. The presentation explores the effects of field solver boundary truncation and boundary conditions. It will give practical guidelines for improving correlation to measurements, both with respect to measurement and simulation strategy. This paper is relevant to everyone using 3D EM solvers.

ALTAIR FEKO EM Simulation Workshop


Trends and Advances in Radio and Radar Coverage Simulation and Planning

Using simulation to predict, analyze, optimize, and plan the coverage given by radio and radar systems is key to reduce development times and costs. Altair Feko offers, thanks to WinProp and WRAP technologies, highly accurate and fast wave propagation models as well as radio network planning modules for almost every standard incl. 5G, allowing the users to perform the radio and radar coverage planning in arbitrary environments including large-scale terrain, built-up, industrial and indoor scenarios.

This workshop will cover simulation strategies for radio and radar networks in complex environments. Examples which are presented during the workshop will include the following ones:
- Planning of 5G private networks in mixed outdoor/indoor environments.
- Evaluation of the installed antenna performance by virtual test drives and flights.
- Effects of interference and jamming on the radio / radar coverage incl. co-existence analysis of radio networks.
