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 ...

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 ...

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 ...

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 ...
