Antennas are essential components of RF and microwave devices and are used in a wide variety of applications including radio and television broadcasting, radar, cellular transmission, and satellite communications to name a few. Antennas are designed to transmit and receive radio waves determined by the design of the application intended to receive the transmissions and ..

RF Antennas Antennas are used to channel radio waves for the purpose of communicating information across distances without wires. Antennas are necessary for a radio receiver or transmitter to convey signals between, for example, radio and television broadcast, cellular networks, Wi-Fi devices, radar and GPS, and remote control devices. Antennas transmit and receive radio waves ..

Electrical losses in a coaxial cable create heat in the outer and center conductors and are the two main types of coaxial cable loss, skin-effect loss and dielectric loss, respectively. This heat, or loss, can be calculated with the understanding of the following concepts. What is Skin Effect Loss? In coaxial cable, skin effect is ..

The coaxial cable provides a transmission line with low loss characteristics that can shield from outside signals and provide a durable yet flexible line that can be used in a variety of applications with a wide range of frequencies.  At microwave frequencies, much of the loss in coaxial cable transmission lines is characterized as metal ..

In the previous sections of the “Coaxial Cable Power Handling” blog series, a brief overview of coax power handling, and how cable size, cable type, signal frequency, and electron velocity through a cable, influenced the power handling capability of a coaxial cable. In this section, attenuation/loss, environmental factors, VSWR, and cable capacitance, will be touched ..
