Designing a Phased Array Antenna Using Antenna Magus and CST STUDIO SUITE

Antenna synthesis lets engineers investigate many potential designs and produce antennas that fit the specifications quickly. For effects that cannot be accounted for analytically such as edge effects and mutual coupling, full-wave 3D simulation can complement synthesis tools and allow designs to be checked and fine-tuned. This article explores the synthesis of an antenna array, using a phased array satellite communications antenna as an example.

3D Printing of Aerospace Parts: A Real Solution with Real Benefits

Innovation in aerospace is accelerating, advancing frontiers at the component and product levels in manufacturing operations, rethinking supply chains and, in some cases, at the business model level. Parts can now be created with complex geometries and shapes that, in many cases, are impossible to create without 3D printing. Low aerospace volumes make 3D printing an attractive, lower-cost alternative to replace conventional CNC machining and other tooling processes for smaller-scale parts and finished assemblies. Aerospace innovators are embracing 3D printing beyond prototyping, and are aggressively pursuing new applications for the technology. This white paper describes how the aerospace industry can reap the many benefits of 3D printing to reduce expenses associated with time, waste, and productivity.

Silicon Avalanche Photodiode

Excelitas’ (Waltham, MA) new HeliX Silicon Avalanche Photodiode (APD) Module is a compact, easy-to-use, analogue low-light-level detection (L³D) module employing Excelitas’ Si APD chips. The detector is in a hermetic TO package, mounted on a practical OEM-based PCB that includes high-voltage power supply, temperature compensation, a low-noise transimpedance amplifier, APD bias monitor and micro- controller. The preamplifier gain is optimized to obtain maximum dynamic range and linearity with the APD at gain adjustable operating voltage. It optimises APD operation in key performance parameters such as higher sensitivity, and better signal-to-noise ratio across the 400nm – 1100nm wavelength range. To learn more, click here.

Tablet Cameras

Motic (Richmond, British Columbia) has figured out a way to turn tablet computers into dynamic imaging stations that will preview, acquire, store, measure, and communicate microscope images. Built on Android technology, Motic’s new line includes two tablet cameras, the 7” Moticam S2 and the 10” Moticam T2. Both Tablet Moticams are managed by Android’s powerful 1.6GHz quad core processors using 1GB of DRAM, and both sport brilliant 1280x800 displays. The S2 provides 8GB internal memory while its bigger cousin boasts 32GB. Because images devour storage, both systems are equipped with Micro SD cards (up to 32GB). They also “play well with others”, readily sharing images and movies via Bluetooth, WiFi, and HDMI connections. To learn more, click here.

Spectrometer Platform

Ibsen Photonics (Farum, Denmark) recently announced the new FREEDOM HR spectrometer platform for integrators of compact analytical and process control instruments. The new HR platform consists of FREEDOM HR-UV, HR-VIS, and HR-VIS-NIR for high resolution down to 0.2 nm in the UV, 0.4 nm in the VIS and 0.6 nm in the VIS-NIR. The size of the spectrometer is only 61 x 64 x 19 mm. All FREEDOM spectrometers can be configured with a range of CCD, CMOS, and NMOS detectors as well as an optional USB controller and accompanying software. The spectrometers are robust and almost athermal and can operate under demanding environmental conditions. To learn more, click here.

Laser Interferometer

4D Technology Corporation (Tucson, AZ) has introduced its newly improved AccuFiz compact laser interferometer for accurate, repeatable measurement of surface shape and transmitted wavefront quality. New features include long- range wireless remote control, motorized tip-tilt and a variable sensitivity alignment system. The wireless remote provides control over instrument set- up, data acquisition and the motorized tip-tilt, for precise system adjustment without disturbing the cavity. The improved alignment system makes it easy to align weakly reflecting samples and high-loss cavities, even in high ambient lighting conditions. The new Surface Isolation Source option adds a second, external laser source to measure plane parallel optical surfaces, without the need for messy coatings or back-surface treatments to eliminate unwanted reflections.

8-Channel Portable Serial Recorder

Pentek, Inc. (Upper Saddle River, NJ) has announced a new recorder for the popular family of Talon® recording systems: the Model RTR 2736A multi-channel Serial FPDP (sFPDP) rugged portable recorder, suitable for military and aerospace, radar, and communications applications. The RTR 2736A is capable of capturing up to 8 Serial FPDP data streams in real time to solid state drives (SSD). It fully complies with the VITA 17.1 specification and additionally supports sFPDP baud rates up to 4.25 Gbaud. The RTR 2736A includes a high-performance PCIe Gen. 3 SATA III RAID controller capable of streaming contiguous data to disk in real time at aggregate rates up to 3.2 GB/sec. The hot-swappable SSD array is available in 1.9 TB to 15.3 TB configurations and supports RAID levels 0, 1, 5, or 6. The new Talon portable chassis for the RTR 2736A boasts a smaller footprint that is lighter in weight, and provides double the storage capacity, number of channels and the recording rates of previous generation of Talon portable recorders. It also supports AC and DC power options. For Free Info Visit http://info.hotims.com/55588-520
