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 ...

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 ...

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 ...

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 ...

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 ...
