Embedded Dual-Band GSM Antenna Design

December 9, 2014
This application note illustrates how CST MICROWAVE STUDIO® (CST MWS), Antenna Magus and Optenni Lab can be used in combination to improve an existing GSM tracking device application. The requirement was to replace an existing “off-the-shelf” antenna on a GSM tracking device with an embedded, integrated antenna in order to reduce manufacturing and component costs.

Investigating Cosite Interference Effects on an Automobile

December 9, 2014
The modern car includes an ever-increasing number of wireless systems. These require an assortment of different antennas, often mounted in close proximity. Coupling between these antennas can lead to cosite interference effects, degrading the performance of the systems or disrupting them altogether. This article demonstrates how a full-wave simulation in CST MICROWAVE STUDIO® (CST MWS) can be combined with RF cosite interference analysis in Delcross EMIT to identify and mitigate EMC/EMI problems.

Analyzing RF Coextistence in a Mobile Handset

December 9, 2014
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.

EMC

March 1, 2012
Several extensions and special solvers are used in FEKO for efficient EMC analysis, e.g. adaptive frequency interpolation, cable harness analysis, SAR calculation, low frequency stabilisation, time domain analysis. Applications include shielding and coupling investigations, reverberation chamber design and EMC test environment modelling.

Antenna Design and Placement with FEKO and Antenna Magus

February 6, 2012
App Note: Antenna Magus
A case study, showing the design of an array antenna for the proximity fuse of an air defence missile, is performed to illustrate the combined use of Antenna Magus and FEKO.

Indoor Channel Measurement and Prediction for 802.11n System

January 17, 2012
Significant improvements in the quality and reliability of indoor WLAN communications are claimed for devices with MIMO technology applying 802.11n standards, which allow users to achieve a theoretical data rate up to 300-600 Mbps on a single transmission. This paper presents an analysis of a commercial 802.11n MIMO 2×3 dual band (2.4 and 5 GHz) system focusing on the operational throughput performance over an indoor environment for Line of Sight (LOS) and Non Line of Sight (NLOS) scenarios. Combined field strength distribution, throughput, and propagation-channel environments are examined, comparing physical measurements with simulation results generated in Remcom’s Wireless InSite.
