Antenna Theory: Analysis and Design

Antenna theory focuses on how antennas transmit and receive electromagnetic waves, which are essential for communication technologies like radio, TV, and mobile phones. It involves understanding the design and analysis of antennas to ensure they effectively radiate or capture signals. Key concepts include frequency, wavelength, and radiation patterns, which determine how well an antenna operates in different environments. By studying these factors, engineers can optimize antennas for better performance, enabling clearer signals and broader coverage in various applications, from personal devices to large-scale broadcasting.
