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.

Design of an Ultra-Wideband High-Power-Microwave Traveling-Wave Antenna

December 9, 2014
In this article we discuss the design and implementation of high-power-microwave (HPM) traveling-wave antenna. The antenna is designed to be driven by a high-power, single-shot signal generator with 1 ns pulse-width at the -3 dB power points, and peak voltage of up to 100 kV. Since the signal generator is equipped with an air-filled coaxial-waveguide output, a coaxial-waveguide to parallel-plates transition was also designed and fabricated.

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.

Planar Structures

March 1, 2012
Microstrip filters, planar antennas and other RF structures are solved efficiently using the planar Green's function. Only the stripline or antenna needs to be discretised with this method. Ground planes are treated implicitly by the formulation and do not add to the number of unknowns.

Windscreen Antennas

March 1, 2012
Antennas are increasingly incorporated into the windscreens of automobiles. FEKO has a special formulation to design the antenna and calculate the effect of the vehicle on the radiation pattern of the antenna.

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.
