Standard whip or rubber duck antennas are extremely common due to their low cost and design simplicity. They work very well for long range transmission when the orientation doesn’t change and ...

A UHF reader antenna that emits radio waves in a circular pattern. These antennas are used in situations where the orientation of the tag to the reader cannot be controlled. Since the waves are moving ...

The research group proposed and tested a nano-antenna that uses the specific optical resonance of dielectric nanoparticles to form a near field of circularly polarized light. This technique bolsters ...

I am not an engineer, but I will offer an answer below. Any of our readers are invited to provide further clarification. A circular-polarized antenna is used to read tags in random orientation. The ...

In response to the changing demands of wireless audio installations, RF Venue has unveiled it CP Stage antenna. Housed in a durable, low-profile enclosure, the CP Stage easily mounts to microphone ...

Test and compare FPV circular polarized antennas to see how they improve signal strength and video quality. Perfect for drone ...

Several readers wrote in following my recent discourse on antenna basics requesting some followup on the subject, particularly in the area of antenna polarization. While not a physicist, I can share a ...

An electromagnetic wave or signal traveling from “here” to “there” has an electrostatic field component that we call its E-field and whose direction we assign as the signal’s polarity. Often, the ...
