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 ...

This 4-part report discusses antenna fundamentals and the various types of antennas used for short range devices. Fundamentals are presented along with practical design principals. It is excerpted ...

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 ...

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 ...

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

Several years ago, my team was given an assignment to measure RF radiation from Low Power CMOS ICs. In this article, I’ll describe the setup we designed and some of the problems we overcame to measure ...
