Business: Rayspan uses meta-material technology that allows for smaller antennas in cell phones, routers and other wireless gear. The technology, which is relatively new, aims to shrink the size of ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Small electronic devices (cell phones, mobile DTV receivers, etc.) demand small antennas, but it ...

InfoChip Systems has developed a solution that it claims not only makes it possible to read very small high-frequency (HF) tags using standard off-the-shelf HF readers, but also enables that to be ...

When it comes to military and consumer electronics, smaller is often better, and the Air Force Research Laboratory’s revolutionary new antenna design is promising to make military electronics much ...

(Nanowerk Spotlight) Electrically small antennas (ESA) find use in a wide variety of communications platforms – e.g. mobile phones an other handheld devices, RFID, aerospace and defense systems – but ...

Electrically small antennas (ESAs) are characterised by dimensions that are significantly smaller than the operational wavelength, which imposes stringent physical constraints on their bandwidth, ...

The purpose of this article is to explain, in detail, the process involved in building and tuning a high-frequency (HF) RFID antenna, which would operate at 13.56 MHz. Some concepts will be explained ...

In this application note we will explore antenna theory and design using EZNEC, an easy-to-use antenna simulator. We will measure the antenna’s characteristic impedance through our application board.

This application note details the variety of antennas that are used in today’s handheld transmitter applications, such as remote keyless entry (RKE) systems, tire pressure monitors (TPMs), garage door ...

The Eclipse is a small, compact TV antenna designed for places like cities with strong TV signals and no room for external antennas. The Clearstream Eclipse is a small, flat TV antenna designed for ...

Radio-wave receivers shrunk to one-hundredth their original size. Metal antennas that send and receive TV signals and radio waves could soon be replaced by tiny films up to one hundred times smaller, ...
