<p>This invention relates a multiservice antenna system integrated in a plastic cover fixed in the inner surface of the transparent windshield of a motor vehicle. The invention includes miniaturized antennas for the basic services currently required in a car, namely, the radio reception, preferably within the AM and FM or DAB bands, the cellular telephony for transmitting and receiving in the GSM 900, GSM 1800 and UMTS bands and for instance and the GPS navigation system. The antenna shape and design are based on combined miniaturization techniques which permit a substantial size reduction of the antenna making possible its integration into a vehicle component such as, for instance, a rearview mirror. At least a first antenna of the antenna system includes a conducting strip or wire, being shaped by a space-filling curve.</p> |
