Half space radiation antenna for UWB ranging and localization application
Integrating the concept of Antipodal Vivaldi antenna (AVA) and planar disc-shaped dipole, a half space radiation UWB antenna is proposed in this letter. The antenna adopted approximately 1/4 of the disc-shaped dipole as its radiator, fed by the AVA's exponential slot structure. The proposed antenna has an ultra-wide bandwidth and nearly half space radiation pattern. This character makes it applicable to UWB ranging and localization field. The antenna analysis and design was carried out by CST software. The prototype was fabricated and experimentally measured. The simulation and measurement result confirms the feasibility of the design.
