3Waveguide — This page is about waveguides in the most general sense. For ordinary metal pipe waveguides, Waveguide (electromagnetism). For optical waveguides, see Waveguide (optics). A section of flexible waveguide with a pressurizable flange …
4Waveguide (electromagnetism) — In electromagnetics and communications engineering, the term waveguide may refer to any linear structure that guides electromagnetic waves. However, the original and most common meaning is a hollow metal pipe used for this purpose.A dielectric… …
5waveguide — /wayv guyd /, Electronics, Optics. n. a conduit, as a metal tube, coaxial cable, or strand of glass fibers, used as a conductor or directional transmitter for various kinds of electromagnetic waves. Cf. optical fiber. [1930 35; WAVE + GUIDE] * *… …
6Power dividers and directional couplers — A 10 dB 1.7–2.2 GHz directional coupler. From left to right: input, coupled, isolated (terminated with a load), and transmitted port …
7Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… …
8Horn antenna — Pyramidal microwave horn antenna, with a bandwidth of 0.8 to 18 GHz. A coaxial cable feedline attaches to the connector visible at top. This type is called a ridged horn; the curving fins visible inside the mouth of the horn increase the antenna… …
9Feed line — The Feed line in a radio transmission, reception or transceiver system is the physical cabling that carries the RF signal to and/or from the antenna. It is also called a transmission line. When operating properly, and under ideal conditions, the… …
10Parabolic antenna — A parabolic satellite communications antenna at Erdfunkstelle Raisting, the biggest facility for satellite communication in the world, in Raisting, Bavaria, Germany. It has a Cassegrain type feed. A parabolic antenna is an antenna that uses a… …
