As wireless devices shrink, antenna design becomes a critical bottleneck. This guide explores several techniques to overcome ...

After building the Yagi, the predicted tuning and impedance matched the real antenna nicely. But what about the radiation pattern? To test that, he used a NanoVNA and a clever test setup.

The center tower features a 10-bay ERI antenna at the top for KLIZ (FM) “The Power Loon,” 100 kW on 107.5 MHz. A three-bay ERI antenna below it serves KUAL (FM) “Cool 103.5” with 20 kW ERP.

Sinclair Broadcast Group-owned Dielectric has literally changed how FM broadcast antenna manufactures validate directional pattern studies for new FM broadcast antennas. In fact, the company's ...

Scientists from the Massachusetts Institute of Technology developed a 2D material that is based on existing rectifying antenna, or rectenna, devices. These capture AC electronic waves from ...

Expanding frequency coverage required increasing antenna height—up to 0.39 times the low-frequency wavelength—which presented a trade-off between stealth and performance.

2D X-ray images can detect major deviations from an expected design, like the presence of an antenna and an IC, but it’s easy to slip other features past a simple 2D X-ray scan… pic.twitter ...

There are a number of issues that come with using a laser to generate excitons within carbon nanotubes. Researchers have now identified ideal nanotube forms that boost light emission from these ...

Crews are set to make repairs on the News 8 transmitting antenna in Orion, Illinois. For some viewers, there will be outages as the transmitter operates at reduced power for crew safety.

3D printing method advances electrically small antenna design March 16, 2011 While most electronic components benefit from decreased size, antennas-whether in a cell phone or on an aircraft-suffer ...
