A model that predicts the radiation pattern from patch antennas in real installations could take the guesswork out of communication device development. A model that predicts the radiation pattern from ...
When broadcasting was in its infancy, amplitude modulation (AM) was the principal modulation system being researched and developed. Once efficient generation of useful RF signals was discovered and ...
The Electromagnetics Group (EMAG) at New Mexico State University's Physical Science Laboratory (PSL) are completing tests centered on obtaining antenna radiation pattern measurements using an inert, ...
No audio available for this content. Applied EM’s anti-jam GPS antenna, AJGPS045, has achieved a four-channel Controlled Radiation Pattern Antenna (CRPA) in a very small size, weight and power (SWAP) ...
Global navigation satellite system (GNSS) technologies such as global positioning system (GPS), GLONASS, COMPASS/Beidou, Galileo, QZSS, IRNSS/NavIC, and others are increasingly crucial for terrestrial ...
No audio available for this content. More satellites, more constellations, more multi-frequency receivers — they all drive greater achievable accuracy. But they also raise the requirements on GNSS ...
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 ...
