Abstract :
We present a novel optically transparent ultra wide band (UWB) disc monopole. The feeding of this antenna is composed by a 50 Omega coplanar waveguide. All the results are analyzed and compared with a non-transparent (but identical) antenna. The antennas are working from 1 GHz up to 8.5 GHz, where the radiation patterns, in both e-plane and h-plane, are plotted for several frequencies. These radiation patterns are omni-directional and monopole-like in h-plane and e-plane respectively, as expected. A gain sweep is measured using coaxial cable and optical fibre for both transparent and aluminium antenna. The proposed antenna uses the highly conductive AgHT-4 transparent film and it is suitable for inter-vehicle communications.
