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 ...

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, ...

Coast Guard Petty Officers 2nd Class Jason McCormack and Austin Essegian, both electronics technicians assigned to the Coast Guard Cutter Munro (WMSL 755), cut and re-terminate an antenna line running ...

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 ...

A one hour webinar focussing on electrically small antennas is being held on 20th October 2009, at 8:00am PDT, 11:00am EDT, 16.00pm GMT. Designed to provide an understanding of basic antenna property ...

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.

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, ...
