| Résumé : |
|
A method allowing the increase of the gain of an Ultra Wide Band (UWB) antenna with the addition of short-circuit wires on particular positions is proposed in this paper. The aim is to destruct the radiations in several dimensions to reconstruct them in another one. With this principle, the gain can be increased from 2dB to 5dB without modifying the global dimensions of the antenna. Firstly, the paper presents the principle of addition of short-circuit wires on a bi-cone antenna and then presents its impact on an UWB antenna working in the frequency band 800MHz - 8GHz : the Shark antenna. The performances of the Shark antenna are compared without and with these short-circuit wires and the advantages and drawbacks involved are discussed |
