PCB, patch antennas

Simulate your antenna before the next PCB revision. Design, test and refine PCB, microstrip and patch antennas before manufacturing another board.

Import your Gerber or CAD geometry, define the substrate, feed and materials, run frequency sweeps, and evaluate how your antenna behaves across the frequencies that matter.

See what changes before you manufacture another PCB

PCB antenna performance depends on much more than the antenna shape alone.

Substrate properties, ground-plane dimensions, feed geometry, antenna position and surrounding hardware can all change resonance, impedance and radiation behaviour.

CENOS : RF lets you investigate these effects in simulation and compare design variations before committing to another physical prototype.

1

Start from your PCB design

Import Gerber X2, STEP or IGES geometry, or build antenna geometry using predefined antenna templates and the integrated geometry editor.

CENOS can also process very thin PCB conductors as 2D surfaces to reduce unnecessary mesh complexity.

• Gerber and CAD input
• PCB stack-up and materials
• Patch, ground and feed geometry

2

Test the parameters that change antenna performance

Run frequency sweeps and compare different antenna configurations without rebuilding the entire simulation setup.

Study how changes in patch dimensions, feed position, substrate, ground plane or surrounding geometry affect the antenna.

• Frequency sweeps
• Parametric studies
• Geometry and material comparisons

3

Evaluate the RF results that matter

Review antenna performance using predefined RF results instead of building the analysis from scratch.

Compare designs using S-parameters, impedance, VSWR, Smith charts, radiation patterns, polarization, electromagnetic fields and current distribution.

• S-parameters & VSWR
• Impedance & Smith chart
• Radiation pattern & polarization

Built for practical PCB antenna development

Use CENOS : RF to investigate PCB and patch antennas used in connected electronics, IoT devices, drones, wearables, industrial equipment, medical devices and other compact RF systems.

From the antenna geometry itself to its placement inside the final product, you can test design decisions virtually before moving to another PCB revision.

Your antenna does not operate alone

A PCB antenna can perform well as an isolated design and behave differently once it becomes part of the final device.

The PCB dimensions change. A battery moves closer. A metal shield is added. The enclosure changes. Another antenna appears nearby.

Simulation lets you include these parts in the model and see how they influence antenna behaviour before the design reaches the lab.

Ground plane and PCB dimensions

Study how board dimensions and ground-plane geometry affect resonance, impedance and radiation.

Substrate and material properties

Compare different dielectric materials, thicknesses and material parameters.

Feed and matching geometry

Investigate feed position, feed networks and geometry changes that affect impedance matching.

Nearby components and hardware

Include surrounding parts to understand how antenna placement changes the electromagnetic field and radiation pattern.

Polarization and radiation

Inspect radiation patterns and axial ratio to evaluate polarization characteristics.

Arrays and multi-port designs

Analyze multiple ports, phase shifts, coupling and periodic antenna configurations.

“TrustPoint’s experience with CENOS has been consistently positive. The software has performed reliably and we appreciate its intuitive functionality. Recent tests on our antennas, which aligned closely with CENOS’s simulations — within approximately 2 dB — underscore the software’s accuracy and value.”

“Tiler explored multiple simulation tools, but found CENOS to be the most user friendly by far. It is really quick to setup multiple studies and iterate the design quickly. We also simulated the designs we have in production already and found very good correlation.”

“The CENOS software has allowed SES to reduce development lead times with a simulation product focused on the needs of RFID and connectivity solutions. We are also now in a position to offer fast turn-around antenna design services allied with our patented technology for rugged industrial applications.”
