The text covers different printed microstrip antenna designs, such as from rectangular to a circular, broadband, dual-band, and millimeter-wave microstrip antenna to microstrip arrays. It further presents a new analysis of rectangular and circular microstrip antenna efficiency, and surface wave phenomena. The book- Covers the latest advances and applications of microstrip antennas. Discusses methods and techniques used for the enhancement of the performance parameters of the microstrip antenna. Presents low power wide-area network (LPWAN) proximity coupled antenna for Internet of Things applications. Highlights new analysis of rectangular and circular microstrip antenna efficiency, and surface wave phenomena. Showcases implantable antennas, H-shaped antenna, and wideband implantable antenna for biomedical applications. The book discusses the latest advances such as the Internet of Things for antenna applications, device-to-device communication, satellite communication, and wearable textile antenna in the field of communication. It further presents methods and techniques used for the enhancement of the performance parameters of the microstrip antenna and covers the design of conformal and miniaturized antenna structures for various applications. It will serve as an ideal reference text for senior undergraduate, graduate students, and researchers in fields including electrical engineering, electronics and communications engineering, and computer engineering.
