Abstract: A traveling-wave circular loop antenna with its phase distribution along the circle of $\bm{l}\bm{\varphi}$ is demonstrated to generate the twisted radio wave. Theoretical formulations of ...

With few exceptions, amateur radio is a notably sedentary pursuit. Yes, some hams will set up in a national or state park for ...

The antenna consists of two quasi-Yagi antenna elements, each with an active dipole, a truncated ground plane reflector and one director. Both director and reflector elements are corrugated, ...
