Radio Frequency Systems (RFS) is a designer and manufacturer of wireless and broadcast cable solutions and accessories. Established in 1900, RFS operates across multiple sectors, including telecommunications, broadcasting, and industries including rail [1] and mining. The company operates factories and R&D centers in Germany and China.
Traveling wave antennas are notably one of the few types of antennas that are normally not self resonant: Electrical waves induced by received radio waves travel through the antenna wire in the direction that the arriving RF signals are travelling. Only electrical waves traveling toward the feedpoint are collected; waves traveling away from the ...

A low loss tangent and low dielectric constant are of importance for the efficiency and the bandwidth of the antenna. The prior art includes an RF MEMS frequency tunable fractal antenna for the 0.1–6 GHz frequency range, [18] and the actual integration of RF MEMS switches on a self-similar Sierpinski gasket antenna to increase its number of ...
Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.

Radiall is a company that designs, develops, and manufactures connectors and associated components for use in electronic applications. The company offers interconnect components, including radio frequency/coaxial connectors and cable assemblies, antennas, fiber optic connectors and cable assemblies, microwave components and cable assemblies, microwave switches, and multipin connectors.
A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...
Hirose U.FL, I-PEX MHF I [a], AMC [2] or UMCC [b] is a miniature RF connector for high-frequency signals up to 6 GHz manufactured by Hirose Electric Group, [3] I-PEX, [4] and others. U.FL connectors are commonly used in applications where space is of critical concern, such as in smartphones and laptop Wi-Fi cards.
