Antenna performance isn't just about the antenna itself. The PCB beneath it is determining range, efficiency, & wireless ...

Antennas used with ground penetrating radar (GPR) come in different shapes and sizes. The largest antennas typically radiate the lower frequencies necessary to detect the deepest targets. The smallest ...

To detect radio signals using a gas, researchers first have to perform a quantum magic trick. They use a sequence of lasers ...

Like much of the world, Australia is shifting from traditional analog television to digital broadcasting. This means new set top boxes if your TV isn't already able to pick up digital signals. But ...

Small ceramic patch elements offer nearly perfect single-frequency receive characteristics and have become the standard for GPS L1 antennas. However, the new generation of GNSS receivers now being ...

Isolation refers to keeping multiple antennas separate from one another to avoid interaction effects. In some devices—especially cell phones, where multiple antennas must be squeezed into a small ...

This is the fourth in a series of articles about FM transmission systems. The bandwidth of a commercial FM broadcast signal, depending on whether or not subcarriers are used, is about 260 kHz. This ...

In recent columns, I've discussed options for TV-transmitting antennas. This month, I'll look at the other end of the path – outdoor TV-receiving antennas. I'll describe desirable attributes for DTV ...
