UHF-Band Folded Antenna Is Suitable For In-Body Wireless Communications
With the implementation of a folded antenna designed to operate in the ultra-high frequency (UHF) band, in-body technology advancements are made possible.
SCMR Enables Efficient Wireless Power Transfer
The strongly coupled magnetic resonance (SCMR) power transfer method is well suited for the transfer of wireless power, achieving significantly larger efficiencies than conventional wireless powering methods.
Radar Detects Disaster Victims’ Heartbeats
NASA and the US Department of Homeland Security have partnered on the development of a portable radar device that detects the heartbeats and breathing patterns of disaster victims trapped in large piles of rubble.
The Do’s And Don’ts Of LTCC
By keeping in mind LTCC’s limitations as well as applicable design rules, engineers can benefit from its use—particularly in compact RF and microwave components.
Interview: SenarioTek Co-Founders Simi Ghiasvand And Bob Alman
Microwaves & RF sits down with SenarioTek's Simi Ghiasvand,CEO & President, and Bob Alman, CTO.
The Case Is Made For WiFi In Hospitals
As long as quality of experience (QoE) levels are maintained, connecting medical devices to a hospital WiFi network can improve clinical workflows by providing wireless access to real-time patient data.
Imagine Yourself As A Network
While full communications technologies are not yet able to be embedded inside individuals, humanity’s large adoption of technology and desire to always be connected does make that future seem inevitable.
Broadband Radio’s LNA Shoulders Harmonic Rejection To 20 dB
This 100-MHz-to-10-GHz harmonic-rejecting LNA introduces harmonic rejection in the front-end LNA to relax the stringent matching required for harmonic-reject mixers.
SiGe BiCMOS Pulsed Radar Opens Door To Imaging And Gesture Recognition
While eliminating any RF or IF phase shifting or combining, this array architecture simplifies scaling to a larger number of nodes.
Space Mapping Outpaces EM Optimization In Handset-Antenna Design
By using a space mapping based modeling and design technique for handset antennas, it is possible to achieve significant time savings over direct EM based optimization.
Interview: Element Six's Adrian Wilson
Adrian Wilson, Head of Element Six's Technologies Division, discusses the firm's GaN-on-diamond technology.
USB Coaxial Switches Aid Test And Measurement
In RF and microwave applications, USB coaxial switches offer various options for measuring multiple DUTs or performing multiple tasks with a single connection.
Get A Handle On Power Handling For SMD Components
This application note concisely presents recommendations for engineers designing a PCB for mounting SMD terminations, attenuators, and resistors.
Wireless Power To The People
While wireless power solutions have been evolving, solar charging solutions could eventually overtake them, given the convenience of not having to use charging pads and other accessories.
UWB RFID System Cuts Coupling By 20 dB
By applying ultra wideband (UWB) technology to RFID applications, it is possible to overcome some of the limitations of the current narrowband RFID technology.
