This paper presents the design of a broadband antenna to be used in a multiple antenna source stirring scenario. Usually, an array of monopole is placed onto the chamber's walls and the antennas are sequentially fed to perform the stirring action. But monopoles are intrinsically narrowband antennas: for this reason the use of a broadband antenna was investigated. The adopted structure is a helix antenna able to minimize the chamber volume reduction and to maximize the averaged power delivered to the chamber. Its performance was investigated by analyzing some typical RC performance indicators.
