All-UWB SLAM Using UWB Radar and UWB AOA

IEEE Robotics and Automation Letters
There has been a growing interest in autonomous systems designed to operate in adverse conditions (e.g. smoke, dust), where the visible light spectrum fails. In this context, Ultra-wideband (UWB) radar is capable of penetrating through such challenging environmental conditions due to the lower frequency components within its broad bandwidth. Therefore,

A Deformed-Film UWB Antenna

IEICE Transactions on Communications, 2010
Recently, microwave ultra-wideband (UWB) technology has attracted much attention in high speed wireless communications, imaging and radar applications. Antennas with very wide impedance bandwidth and stable radiations are required for such systems. Among many UWB antennas, planar types are low profile, light weight, low cost and suitable for mobile ...

A 0.7 to 30 GHz Coplanar Vivaldi Antenna

Microwave and Optical Technology Letters, Volume 68, Issue 8, August 2026.
ABSTRACT In the literature there are multiple Vivaldi antenna designs that have a wide impedance bandwidth; however, the usable bandwidth is often limited by pattern degradation at the higher frequencies of the band. This paper presents the design and implementation of a coplanar Vivaldi antenna with a 42.9:1 usable bandwidth ratio (0.7–30 GHz).
