Antennas are an essential component of modern communication systems, used to transmit and receive electromagnetic waves. These devices have played a vital role in the evolution of wireless communication technology, from the early days of radio to the present-day 5G networks. Antennas come in different shapes and sizes, each designed to serve a specific purpose and frequency range. They can be found in various applications, including mobile phones, televisions, and satellite communication systems. Understanding the principles of antenna design and operation is critical to developing efficient and reliable wireless systems.
