In this study, an ultra-wideband cavity-backed four-arm sinuous antenna with low height and wide gain bandwidth is proposed. To reduce the antenna height, a feeding structure is applied with a coaxial bundle and two-port balun. In addition, a multi-layer radio absorber and metallic cavity are applied to obtain certain characteristics, such as a unidirectional radiation pattern, low profile, and stable reflection coefficient. Additionally, a radiator with low input impedance is applied for a wide gain bandwidth. The proposed antenna operates at 0.4～6.0 GHz and has a relatively low height and large gain bandwidth compared to the performance of previously studied antennas. [ABSTRACT FROM AUTHOR]
