We all use antennas for radios, cell phones, and WiFi. Understanding how they work, though, can take a lifetime of study. If you are rusty on the basic physics of why an antenna radiates, have a look ...

The Siekoh Giken OEFS (Optical Electric Field Sensor) optically-coupled E-field probe is a very unique instrument (Figure 1). The company has developed a technology whereby the amplitude and frequency ...

Southwest Research Institute (SwRI) is expanding its antenna measurement capabilities with a state-of-the-art spherical near-field antenna range. The 1,260-square-foot indoor range, lined with radio ...

The Next Innovation In Winegard’s GETDTV/HDTVTM Antenna Series For Indoor Reception of DTV/HDTV Broadcasts Burlington, Iowa, November 23, 2004. The right Off-Air DTV/HDTV Antenna is now a Necessity, ...

When Scotty is beaming up, he’s working in the very far field. Distinguishing between near field and far field conditions is especially important in EMC testing. Published antenna factors and related ...

Needing an E-field meter and wondering how the more inexpensive ones compare to those costing thousands of dollars more, I purchased the Extech model 480836 handheld meter at $279 to characterize the ...

If you need to generate a radio frequency electrical signal, you will make some form of electronic oscillator. We’ll probably all be used to oscillators using transistors, tubes, logic gates or a host ...

SwRI’s 1,260-square-foot indoor spherical near-field antenna range is equipped with a built-in overhead half-ton hoist to install and test large antennas up to 10 feet in diameter and 1,000 pounds.
