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 ...

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 ...

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) ...

GPU-accelerated electromagnetic simulation is redefining how engineers design and validate antennas in complex, electrically ...

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 ...

Radiation patterns for antennas can be utterly confusing, especially when presented in two dimensions, as they usually are. Fear not, [Hunter] has your back with 3D printed and color-coded radiation ...

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 ...

Measuring antenna gain patterns is a critical part of evaluating the performance characteristics of an antenna under test. A software-defined radio (SDR) is an economical and flexible radio system ...

Placing an antenna in a design always needs care, but when there are two or more antennas in the design, it is even more important to understand how the antennas radiate, how they will perform ...

This article was written by Louis Frenzel, author of Principles of Electronic Communications Systems, that addresses this topic and much more. Antennas are much more than simple devices connected to ...
