This article presents the experimental study of a ultra‐wideband (UWB) active antenna comprising of a chaotic oscillator coupled to a dielectric resonator antenna. Wideband spectrum properties of chaotic signals are used to design an UWB active antenna. In contrast to classical active UWB antenna designed using patch, the proposed active antenna is capable of enhancing the bandwidth, easy to integrate with the oscillator and is small in size. The proposed UWB antenna using DR can be employed in UWB wireless communication systems.
