Wide-Band Short Backfire Antenna
The short backfire antenna (SBA) has been widely used for mobile satellite communications, tracking, telemetry, and wireless local-area network applications due to its compact structure and excellent radiation characteristics. The SBA consists of a pair of reflectors and a circular rim and, is excited by an H-shaped slot which has been cut on a rectangular patch. The H-shaped slot is centre-fed at one side of the slot by a cylindrical wire probe that has been extended from the inner conductor of a coaxial line...
Autonams Selects Nordic's 2.4GHz Transceiver For Car Immobilizer Systems

Application Note: Automotive Sensors
A modern car
has numerous microprocessor-controlled electronic sensors and actuators that carry out complex
measurement, monitoring and control tasks. An indispensable tool in the development and
production of these silent assistants are modern, non-contact optical metrology processes
Application Note: Quality Control
TRW Automotive in Gelsenkirchen wants to ensure that the pumps on hydraulic steering gears do not make any unwanted noises while driving. Based on the vibration spectrum the process controller either approves the assembly for subsequent processing or rejects it as being faulty
Application Note: Transfer Path Analysis
What kind of a noise is made when the surface of a component vibrates? What path does the noise take to your ear? What component vibration is most undesirable? These are the questions that employees at Polytec and HEAD acoustics are currently trying to solve within the framework of a joint project
Application Note: Break Squealing
Optimizing automotive noise behavior is an important aspect in new vehicle designs. Using Polytec's innovative measurement technology, researchers at Robert Bosch GmbH have managed to track down the causes of undesired noises when braking
Application Note: Automotive 3D Dynamics
The PSV 400-3D presents a huge potential for time saving as compared to accelerometers. It furthermore shows all the known advantages of laser scanning
vibrometers, such as high point densities, non-contact measurements and ease of setup. This article contains the description of the measurements and their results
