Abstract

The design and application of radio frequency (RF) filters are critical to achieving the desired performance, efficiency, and quality expected of the signal from the system in modern communication systems. The rapid expansion of wireless communication technologies and the growing complexity of signal processing requirements underscore the importance of advanced RF filter designs. The quest for higher performance and greater efficiency in emerging communication systems has intensified research into novel filter architectures and materials, aiming to address the evolving demands of modern applications. This paper provides a comprehensive review of the basic principles, design methods, and diverse applications of RF filters across many different communication systems. In addition, it analyzes miniaturization, high selectivity, and broadband challenges faced in current designs, and investigates the potential of new materials and technologies to improve filter performance. The results indicate that with the continuous progress of emerging communication technologies such as 5G and 6G, RF filters have a broad development prospect in the fields of mobile communication, satellite communication, and terahertz communication, which plays a key role in future communication systems.
