This paper presents a detailed review of UltrawideBand (UWB) antennas having band notch characteristics. Each technique used has its advantages and limitations. Among the different techniques applied for eliminating the same number of frequency bands, some can get a good radiation pattern. A few techniques exhibit a low group delay and others have achieved a good gain. The review will aid designers to have a broad overview of the different technical parameters such as gain, operating frequency (bandwidth), radiation efficiency, number of notches produced, and the respective techniques used to model each notch, and size in different types of UWB antennas.
