We’ve known a few people over the years that have some secret insight into antennas. To most of us, though, it is somewhat of a black art (which explains all the quasi-science antennas made out of ...

The Antenna Research Group (ARG) at the University of Colorado Boulder is housed in the Department of Electrical, Computer, and Energy Engineering. ARG’s research specializes in antenna theory and ...

Radio- and microwaves can be generated by currents that oscillate within antennas driven by high-frequency voltage sources that extend up into the 100 GHz regime. Sources for optical and infrared ...

This article describes the phases for the construction of a Yagi antenna. The calculations of the parameters are made using 4NEC2 software. This type of antenna is used for transmissions and ...
