scope

The Radioengineering journal makes an effort to encourage a younger generation of scientists and engineers. The journal offers them their first publication opportunity and gives them their first experience in writing a scientific paper. Independent reviewers carefully review each submitted paper, and attempt to explain its stronger and weaker aspects to the authors in detail. Each December and June, the Radioengineering journal prepares a special issue focused on a selected topic of importance and current interest. (source)

Radio-frequency engineering

Radio-frequency engineering is a subset of electrical engineering that deals with devices that are designed to operate in the radio frequency (RF) spectrum. These devices operate within the range of about 3 kHz up to 300 GHz.

Radio-frequency engineering is incorporated into almost everything that transmits or receives a radio wave, which includes, but is not limited to, mobile phones, radios, Wi-Fi, and two-way radios.

Radio-frequency engineering is a highly specialized field falling typically in one of two areas:

providing or controlling coverage with some kind of antenna/transmission system
generating or receiving signals to or from that transmission system to other communications electronics or controls.
To produce quality results, an in-depth knowledge of mathematics, physics, general electronics theory as well as specialized training in areas such as wave propagation, impedance transformations, filters, microstrip circuit board design, etc. may be required. Because of the many ways RF is conducted both through typical conductors as well as through space, an initial design of an RF circuit usually bears very little resemblance to the final optimized physical circuit. Revisions to the design are often required to achieve intended results.

Early radio-frequency engineers

Main articles: Invention of radio and Timeline of radio
Many notable individuals[citation needed] have contributed to the advancement of Radio-frequency engineering theory and design, including the following:

Heinrich Hertz, demonstrated the existence of radio waves and developed the unit of measure to describe frequency of a wave.
Nikola Tesla, known for his high-voltage, high-frequency power experiments in New York and Colorado Springs. Tesla's primary interest was wireless power transmission through a medium (primarily the Earth) with demonstrations in 1893 in St. Louis, Missouri, at the Franklin Institute in Philadelphia, Pennsylvania, and at the National Electric Light Association but saw communication as a side aspect.[1]
Guglielmo Marconi, who developed the first successful commercial wireless telegraphy system based on air-born radio frequency waves (called Herzian waves at the time)[2] and transmitted the first radio signal across the Atlantic Ocean.
Phillip H. Smith, who developed a graphical method of calculating impedances, admittances, reflection coefficients and scattering parameters.
