Recent advancements underscore the potential of plasma antennas in revolutionising electromagnetic wave propagation. Pioneering work has shown that plasma arrays can focus and boost ...

It was one thing for me to build a dish antenna to pick up ... At shortwave frequencies, distant propagation is much more common. Shortwaves travel via ground wave (short distance) and sky wave.

1. An antenna produces both electric and magnetic fields that are perpendicular to one another, as well as to the direction of propagation. What are some of the characteristics of a radio wave?

Remcom announces a new version of Wireless InSite 3D wireless prediction software with advanced capabilities including ...

In this article, I will cover various aspects of millimeter wave (mmW) beamforming and antenna technology with what I consider ... TDD and found that if robust operation across a wide variety of ...

Ground wave radio propagation along the surface of the Earth ... and can only use a three-meter long antenna. While that’s fine for playing around, there’s little chance of being heard ...

A radio wave comprises an electric field perpendicular to a magnetic field. Both are perpendicular to the direction of propagation (Fig. 1). An antenna creates this electromagnetic field.
