Analyzing RF Coexistence in a Mobile Handset

A typical smartphone handset can contain numerous different RF systems, including multi-band cellular antennas, Wi-Fi, Bluetooth, NFC and navigation systems such as GPS and GLONASS. All these systems need to be able to coexist without causing cosite interference. This application note shows how CST STUDIO SUITE® and Delcross EMIT can be used to investigate interference between antennas on a smartphone, and how potential mitigation strategies can be investigated using simulation.
