Characteristic mode analysis (CMA) to provide new insights that would be difficult to obtain otherwise. CMA provides insights into physics of the problem, as it produces the radiating current modes that fit naturally on a given geometry. This application note discusses how CMA insights may be used to improve performance of an ultra-wideband antenna.
Many designers will find Optenni Lab useful in creating antenna designs that will conform to any impedance requirement. This application note talks about the Optenni Lab, and examples of its use and value in the design of a DVB antenna, and a compact GPS and Wi-Fi Antenna.
Carrier aggregation (CA) enables mobile network operators worldwide to provide faster data, and allows mobile devices to communicate on multiple LTE bands simultaneously. This, however, creates the challenge of avoiding interference between the bands while keeping up good reception and battery life. Multiplexers are an excellent solution for CA combinations that use closely spaced bands since they provide isolation between and within bands, while allowing them to connect to the antenna at the same time. This white paper discusses the challenges of carrier aggregation, and the important benefits of using multiplexer solutions to solve them.
This application note discusses how co-located MIMO performs as well as or better than spatially separated SISO antennas while providing a cheaper alternative.
The new device is FDA approved and, like the anti-theft radio frequency tags used in stores, it acts like an antenna and responds to infrared radio signals.
NOEMA (Northern Extended Millimeter Array), the most powerful millimetre radio telescope of the Northern Hemisphere, has unveiled its first astronomical image: a unique and spectacular view of a previously unknown region of extreme star formation in the ‘Medusa merger’ – a luminous collision of two galaxies at more than 100 million light years from Earth.
Ethertronics has announced a complete Wi-Fi Active Steering antenna system solution that improves network performance by up to 3 dB for a wide-range of Wi-Fi devices including access points, set-top boxes, smart gateways and the Internet of Things. The company will demonstrate at CES 2016 in Las Vegas, January 6-9, 2016, its new 5 GHz Wi-Fi reference design platform.
Anritsu Company expands its Electromagnetic Field (EMF) Measurement System with the introduction of isotropic antennas that provide frequency coverage from 9 kHz to 6 GHz. The new antennas support measurements of EMF radiation to ensure wireless networks are in compliance with various national standards for personal safety established by government regulatory authorities.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have measured the mass of the supermassive black hole at the center of NGC 1097 -- a barred spiral galaxy located approximately 45 million light-years away in the direction of the constellation Fornax. The researchers determined that this galaxy harbors a black hole 140 million times more massive than our Sun.
Scientists from the Harbin Institute of Technology in China have proposed a new way to maintain communication with spacecraft as they re-enter the atmosphere. The approach might also be applied to other hypersonic vehicles such as futuristic military planes and ballistic missiles.
The demonstration example, using Freescale radar ICs on Astra MT's advanced thermoset dielectric material for millimeter-wave automotive radar, will be demonstrated at the International Microwave Symposium (IMS) 2015. The , and will highlight Astra MT material's reliable electrical performance in wide field-of-view radar applications for automotive systems.
For decades, the fundamental design of microwave devices, such as antennas for mobile communication and waveguides used in radars, has essentially relied on the inventiveness of a professional designer.
