The following is excerpted from Chapter 3: Radio Basics for UHF RFID from the Book, The RF in RFID: Passive UHF RFID in Practice by Daniel M. Dobkin. RFDesignLine readers who order a copy of this book ...

We have been able to conclude that using an isotropic antenna, an RFID reader might achieve a read range of a few meters with 1 watt of output power. This configuration might be fine if RFID tags of ...

The purpose of this study is to assess the mean RF power radiated by mobile telephones during voice calls in 3G VoIP (Voice over Internet Protocol) using an application well known to mobile Internet ...

Quasi-isotropic antennas are designed to deliver uniform radiation in almost all directions, thereby ensuring optimal signal coverage in complex communication environments. These antennas are pivotal ...

This is a very technical question. Since I am not an RF engineer, I reached out to a few people for the answer. Before I provide an answer, let me explain what the terms mean, for those who don’t know ...

Poor PCB track layout isn�t the only culprit causing radiated EMI. Here are some simple design techniques that can reduce EMI from high-speed ASICs. Electromagnetic interference (EMI) is a latent ...
