Companies have been looking for ways to improve antennas: increased efficiency, increased bandwidth and ways make them smaller. Techniques include fractal antennas, electronically tuned antennas, ...

All aircraft start out looking sleek and graceful. Then comes the avionics department, and their sleekness diminishes because every surface seems to have an antenna attached. Large or mission-specific ...

The field of filtering antennas integrates antenna design with filtering circuits, thereby achieving simultaneous radiation and frequency selectivity. These systems are engineered to transmit or ...

Thanks to an innovative extension to 3D printing, researchers can create high-performance, low-weight “unbuildable” RF structures that combine dielectrics and patterned conductors. The benefits and ...

This application note is intended for designers who are incorporating RF into Part 15-compliant designs. It is designed to give the reader a basic understanding of an antenna’s function, operational ...

Fig. 1 | Schematics of the PA-PSO algorithm. (a) and (b) Working principle of the metalens antenna. (c) and (d) Comparison between the traditional PSO and PA-PSO algorithm. The red and blue stars ...

Placing an antenna in a design always needs care, but when there are two or more antennas in the design, it is even more important to understand how the antennas radiate, how they will perform ...

I have always been amazed by how much difference a good antenna makes in a wireless application. It became pretty clear to me at an early age as a ham radio operator that a good antenna is the ...

Here is an antenna researchers were able to shrink in size. Researchers at the Air Force Research Laboratory, working with Northeastern University, recently developed an ultra-compact antenna that ...

The very mention of RF design is usually enough to scare all but the most confident designer. However, wireless specialists such as the company I work for, Nordic Semiconductor, have worked hard to ...
