Antenna structure for electromagnetic structures

The invention relates to an antenna structure for transmitting and receiving electromagnetic signals, in particular for mobile telecommunication using the GSM Standard. One task of the invention is to provide an antenna structure which results, in particular, in decoupling between the transmission path and reception path. The object is achieved by the invention in that the antenna structure according to the invention has two preferably perpendicular couplings with two separate ports, for example for the connection of a transmitting device and a receiving device. Furthermore, the impedances of the two couplings can advantageously be matched, independently of one another, to the transmitting device and receiving device and/or the frequency bands of the signals to be transmitted or received.
