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 ...

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 ...

If you’ve ever worked at a station that’s installed a new antenna, you’ve probably wondered how well the antenna’s real pattern matched the nice clean pattern supplied by the antenna manufacturer. The ...

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 ...

When [Jephthai] wanted to build his own Yagi antenna, he turned to MMANA software for antenna modeling. This is an antenna analysis program that uses the moment method to calculate parameters for ...

The Electromagnetics Group (EMAG) at New Mexico State University's Physical Science Laboratory (PSL) are completing tests centered on obtaining antenna radiation pattern measurements using an inert, ...

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 ...

On California’s Mt. Wilson, dual RFS broadband panel arrays provide sculpted digital/analog signals for four broadcasters. With the launch of digital terrestrial television (DTT) has come a generally ...
