5G RedCap: RF Implications for IoT Devices

The global transition to 5G is in full swing. Although 5G has primarily been used for smartphones and FWA applications, its potential applications are much broader. 5G will expand in scope to cover many more applications and device types. 5G Redcap will be a key step in this evolution.

Why Use Planar Inverted-F Antennas (PIFA) for Compact IoT Devices?

Increasing use of small wireless applications, such as Bluetooth, Wifi, Cellular, Positioning, brings challenges to integrate the antennas with maintained performance. There are several techniques for miniaturization of antennas with pros and cons. This paper presents how the PIFA technology can combine small size with good performance and frequency stability.

Electromagnetic Simulation for Electronic System Design in Aerospace and Defense

The aerospace and defense industry relies heavily upon advanced electronic systems for field communications, control, targeting, threat detection, asset tracking, health monitoring, and theater operations. These advanced electronic systems often require multiple, high-fidelity antennas. Those antennas, in turn, require interference free integration for maximum signal strength and reliability. This technical document provides an overview of Altair’s electromagnetics simulation strategies and technologies that support the development of complex electronic systems.

How to Measure and Reduce Common Mode EMI in Electric Drive Installations

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
