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 research group from Kobe University in Japan have proposed and tested a nano-antenna that uses the specific optical resonance of dielectric nanoparticles to form a near field of circularly polarized ...

How are they different? I have read a lot about this, but I still can’t differentiate much between them. The difference is very simple. A linear-polarized antenna is designed to concentrate RF energy ...

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 ...

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 ...

Researchers developed and tested a deployable antenna for the 3U CubeSat OrigamiSat-2. Weighing only 64 grams and achieving a storage ratio of 265%, the antenna enables CubeSats to transmit data at ...

THE ANTENNA. This crucial component of any radio transmitting or receiving system has a history that actually predates the invention of radio itself. The first antennas were used by Princeton ...

These days, when it comes to GPS devices the antenna is typically part of the package. But what better opportunity for [Pepijn] to learn how to make a GPS antenna from scratch for a badge add-on? A ...
