摘要
Antennas are critical components for wireless connectivity.In general,antennas with a wide bandwidth,compact size,and high efficiency are required in order to achieve a high level of system performance with modern wireless communication systems,sensor networks,radio astronomy,deep space probes,and so on.The importance of antennas is reflected by the numerous research articles that have been published on this topic in recent years—not only in antenna journals,but also in other related journals on sensors,vehicular technologies,microwave techniques,and terahertz techniques.The huge number of downloads for the papers published in major antenna journals also demonstrates the attractiveness of antenna research.
