ADS: Using layout parameters in Momentum EM simulations

Published on 13, Nov

In this application note, we will look at two different ways of using layout parameters for Momentum EM simulations: Use built-in parameters in layout created from standard circuit elements (microstrip line etc.) Parameterize manually drawn layout from rectangles/polygons We will discuss the use EM results of parameterized blocks in a schematic, with emSetup/emModel views. A […]

Microwave Office: PCB antenna simulation 868MHz

Published on 23, Jan

In part one of this application note we had discussed basic design concepts and simulation methods for “printed” PCB antennas. Now in this second part, we will discuss advanced topics: Co-simulation of antenna and SMD matching components for electrically small antennas Using the Analyst 3D FEM solver to include the effect of finite PCB size, […]

Microwave Office: PCB antenna simulation 2.4GHz/5.6GHz

Published on 16, Jan

This document describes the design and simulation of simple PCB antennas for 2.4GHz and 5.6GHz with Microwave Office and the Axiem EM simulator. The first example shows a 2.4GHz single band antenna. The second example then shows a dual band version for 2.4GHz and 5.6GHz. Finally, we will investigate the sensitivity to PCB material tolerances. […]

Momentum port: global ground or differential?

Published on 6, Apr

There are some good uses for ports with an explicit (-) ground reference. Using them for SMD elements, where a device is included as 1-port with (+) on one pad and (-) on the other pad, is not a good idea in most cases. Used in the wrong context, you can get totally unexpected results […]
