<p>The invention relates to an antenna, characterised in comprising a generator and at least two parallel metallic surfaces, substantially superimposed one on the other. At least one of said surfaces is divided into at least two concentric parts, comprising a central part and a strip surrounding said central part, said at least two parts are connected by means of one or several conducting strips, the at least two parts of the divided surface include one part connected to a first generator terminal and one part connected to a second generator terminal. The above structure confers a multi-function behaviour on the antenna.</p> |
