Design Antennas for Smart Devices Using Altair EM Solution
In an interconnected world, most devices are currently wireless with several antennas. PCBs are densely packed with components, leaving a very limited space for antenna and the engineer needs to come up with a suitable design. The performance of the antenna is also influenced by the adjacent components on the PCB.
This webinar presents Altair’s advanced computational tools for designing antennas on PCBs for Bluetooth and Wi-Fi applications.

First-time-right Design of Matching Circuts for Complex Antenna and RF Applications
Presentation by Jussi Rahola, CEO of Optenni.
The modern mobile phones and other wireless devices, matching circuits are commonly used to tune the antenna to operate at the desired frequencies and to broaden the operation frequency range of the antenna.
The goal of matching circuit design is actually not to get the best possible impedance match (which can be achieved with adding resistive losses), but to maximize the transfer of energy between the amplifier and the antenna. In multiantenna systems also the coupling between the antennas needs to be considered as it will reduce the efficiency of the antenna systems. For the accurate design of matching circuits realistic component models of inductors and capacitors need to be used. Also, the effect of the circuit layout, i.e. the connecting lines and nearby metallization of the PCB near the matching components needs to be considered carefully.
The layout can be modelled using short segments of microstrip transmission lines or using a multiport electromagnetic simulation model of the layout part of the PCB. Thus, armed with the proper tools, such as the Altair Feko electromagnetic simulator and the Optenni Lab RF Design Automation Platform, antenna designers can obtain first-time-right designs for matching circuits, giving a good agreement between simulated and measured results.

First-Time-Right Design of Matching Circuits for Complex Antenna and RF Applications
In the webinar, the sources of the discrepancy between measurements and simulation will be identified. We will demonstrate a first-time-right design flow of matching circuit using the FEKO electromagnetic solver and the Optenni Lab RF Design Automation Platform. The most critical design areas are the accurate representation of the matching circuit layout, using realistic component models, correct calibration and reference plane in measurements and taking the radiation efficiency and multiantenna radiation patterns into account.

Electromagnetic Simulation Growth in the Product Development Cycle
Product development is becoming more challenging due to stricter regulations, and reduced development times and budgets for prototyping and testing. The necessity to add more electronics into new products is making their design more challenging and sensitive to electromagnetic phenomena and effects.
This 40 minute webinar will show how different EM software tools are used in different processes and workflows to tackle these product design challenges.
