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 ...

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 ...

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 ...

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

A controlled radiated pattern antenna can be an effective way to protect GPS receivers against jamming. A new CRPA, composed of seven elements, works on the E5a, E5b, E6, L2, and L1 bandwidths. This ...

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 authors are president and vice president, respectively, of Communications Technologies Inc., a consultancy in Marlton, N.J. Fig. 1: Measured vertical (purple) and horizontal (blue) field strength ...

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 ...
