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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

This antenna tuning unit (ATU) enables half-wavelength or longer wire antennas to be matched to the 50-ohm antenna input of 27-MHz Citizens’ Band (CB) rigs. The ATU is useful in those cases where a ...
