This paper describes the effects of various quality variables on microwave antenna performance, and provides insight into the long-term consequences of using a low-cost/ poor-quality antenna. It demonstrates the effect of operators’ preference for low-cost antennas without considering the total cost of ownership, as well as possible ill effects on their quality of service.
In this work, a high-gain broadband printed Yagi directional antenna for applications in ISM bands (686 and 915 MHz) is presented. The proposed antenna was designed to be implemented in a wireless system, devoted to water and wastewater level and underground flow measurements.
A printed reflectarray is a high-gain, low profile, low-cost antenna that combines the advantages of parabolic reflector antennas with microstrip arrays. This white paper demonstrates how to easily create a printed reflectarray and its simpler feeds through the use of FEKO simulation software.
This application note discusses how co-located MIMO performs as well as or better than spatially separated SISO antennas while providing a cheaper alternative.
Radio Frequency Systems (RFS), the global wireless and broadcast infrastructure specialist, has announced the next phase of its compact, high-reliability ShareLite Combiners.
Radio Frequency Systems (RFS), the global wireless and broadcast infrastructure specialist, recently announced the availability of a field-installable 4.3-10- style connector as a supplementary offering to the existing factory-fit jumper orientations.
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 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.
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.
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.
