Ap Note: Design of Near Field Antenna System

 

National Instruments has released a short application note on how to design a near field antenna system for near field communications (NFC). MFC is a non-contact communication between wireless devices and things, such as, pay terminals or to share information between devices. Examples would include the Apple Pay and Google Pay process. The ap note describes how the antenna … [Read more...]

Association Proposal for Combating Interference

 

The Space Data Association, comprised of the world’s major satellite communications companies, announced the launch of a new geolocation support service to help identify the geographical origin of transmissions to a satellite. The new service will allow members to share resources and expertise to locate sources of interference. Interference continues to be a problem for … [Read more...]

New Units Converter App Available

 

Aaronia AG, maker of low-cost innovative antennas and spectrum analyzers, has recently made available a units converter app for their near-field probes (models H1, H2, and H3). The app will convert the dBm measurement to Tesla, Gauss, or V/m, depending on the probe used. The app may be downloaded from iTunes, here.   … [Read more...]

3D RF Tracking Array Antenna

 

Aaronia AG has announced a new 3D RF signal tracking antenna based on an array of their log-periodic antennas. The basic frequency range is 680 MHz to 6 GHz, and may be extended down to 9 kHz with the addition od an array of loop antennas and as high as 40 GHz with optional antennas. The IsoLOG 3D 80 includes 16 antennas with a resolution of 8 sectors in azimuth. The IsoLOG 3D … [Read more...]

Graphene Used to Manipulate and Control Electromagnetic Radiation

 

Recently, the University of Exeter provided research demonstrating how graphene’s properties can be utilized to create artificial structures that can be used to control and manipulate electromagnetic radiation over a wide range of wavelengths. Scientists at the University of Exeter “combined nano-ribbons of graphene, in which electrons are able to oscillate backwards and … [Read more...]

LTENA Conference Discusses Challenges and Advancements of Antennas

 

The LTE North America conference recently discussed the evolving environment of antennas and their contributions to the functionality of wireless networks, according to RCR Wireless News. Tony DeMarco, chief product officer and GM for Matsing’s base station antenna unit, introduced a spherical antenna, which is said to offer improved performance for roughly equivalent weight … [Read more...]
