In this paper the design and experimental validation of a 2×1 linearly polarized patch array for Car-to-Car communications is presented. The antenna operates in the 5.850-5.950 GHz frequency band and has been designed to be integrated in a car windscreen. Thanks to the presence of the glass superstrate, a valuable miniaturization effect has been obtained. On the other hand, surface waves excited into the glass superstrate reduce antenna gain, and surface wave diffraction injures radiation pattern too. In order to limit above phenomena, a square copper ring film has been printed on the same plane of the radiating elements. To compensate for the windscreen inclination respect to the ground, a proper phase shift between the currents of the two radiating elements has been considered.

Abstract
In this paper the design and experimental validation of a 2×1 linearly polarized patch array for Car-to-Car communications is presented. The antenna operates in the 5.850-5.950 GHz frequency band and has been designed to be integrated in a car windscreen. Thanks to the presence of the glass superstrate, a valuable miniaturization effect has been obtained. On the other hand, surface waves excited into the glass superstrate reduce antenna gain, and surface wave diffraction injures radiation pattern too. In order to limit above phenomena, a square copper ring film has been printed on the same plane of the radiating elements. To compensate for the windscreen inclination respect to the ground, a proper phase shift between the currents of the two radiating elements has been considered.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
