Abstract :
We have investigated leaky-feeder, Ultra Wide Bandwidth antennas based on standard semi-rigid coaxial cable where axial slots are used to form a Babinet dipole antenna array. The slot function, array effect and slot spacing define both the radiation pattern and array bandwidth. Simulations based on Microstripes modelling software predicted the radiation characteristics whilst multi-GHz coherent time domain reflectometry was used to investigate slot size and spacing effects.
