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.
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.
This application note discusses how co-located MIMO performs as well as or better than spatially separated SISO antennas while providing a cheaper alternative.
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.
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.
Ethertronics has expanded its portfolio of active antenna RF switches with the industry’s highest linearity for LTE smartphones, devices and other Internet of Things (IoT) applications. The EC686 and EC646 are designed to meet the market demand for smart Active Steering antenna systems, which dramatically improve performance by increasing data throughput, reducing dropped calls and minimizing the antenna footprint needed for today’s multiband LTE and LTE Advanced smartphones.
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.
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.
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.
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.
Pharad is exhibiting at SOFIC 2016 its new cut to tune antenna for covert vehicle installations. The VHF to UHF antenna can be tuned by the user to most police, public safety, and push to talk radios operating from 130 MHz to 550 MHz.
Antenova Ltd, manufacturer of antennas and RF antenna modules for M2M and the Internet of Things, is announcing three brand new flexible printed circuit antennas to cover the 3G, 4G and LTE bands. These brand new products are the company's first flexible antennas for 4G and LTE.
