Radio Antenna Fundamentals and Characteristics
Text is an extensive Wikipedia article focusing on the radio antenna (also known as an aerial), which is defined as a device converting alternating current into radio waves during transmission or vice versa during reception. Provides a detailed technical overview of antenna engineering, including historical context, fundamental concepts like reciprocity, and resonant antennas. Major sections are dedicated to characterizing antennas based on performance measures such as gain, efficiency, bandwidth, impedance matching, and radiation pattern. Furthermore, the article explores the effect of ground on antenna performance and provides a classification of various antenna types utilized in telecommunications.
