If you want to analyze an antenna, you can use simulation software or you can build an antenna and make measurements. [All Electroncs Channel] does both and show you how you can do it, too, in the ...

An antenna is an electrical component that is needed to transmit and receive electromagnetic energy from the space surrounding it in order to establish a wireless connection between two or more ...

What does a VNA measure? What can one do with the measured data? What devices are measured with a VNA? Most design engineers are familiar with tools of the trade such as voltmeters, oscilloscopes, ...

With the acceleration of Internet of Things (IoT) devices and the proliferation of RF and wireless products, there is a growing need for RF measurement expertise and affordable RF test instrumentation ...

An overview of antenna design considerations is presented. The design considerations include system requirements, antenna selection, antenna placement, antenna element design/simulation, and antenna ...

If you want to deliver the maximum power to a load — say from a transmitter to an antenna — then both the source and the load need to have the same impedance. In much of the radio communication world, ...

The author is senior technologist at NPR Labs in Washington. Field strength measurements are almost as old as radio itself, as engineers have endeavored to test and improve their RF transmission ...
