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 ...

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 ...

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 ...

Compact, rapid-deploy XY antennas assemble in the field without tools and include built-in ACUs for ease of operation.

This article was written by Louis Frenzel, author of Principles of Electronic Communications Systems, that addresses this topic and much more. Antennas are much more than simple devices connected to ...
