StarLab is a near-field multi-sample system with spherical geometry. Antenna radiation patterns in the far field are obtained indirectly by sampling the field near the antenna. The sampled near field ...

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 ...

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 ...

An antenna is an electrical component that is needed to transmit and receive electromagnetic energy from the space surrounding it in order to establish a wireless connection between two or more ...

In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...
