In this study, a low profile wideband 3D antenna for roof-top LTE vehicular applications is presented. The structure consists of folded metal sheets welded together building a geometry that allows covering two LTE bands: 700MHz-960MHz, 1700MHz-2700MHz. The shape and the size of the antenna allow to fit it under the shark-fin case, and thanks to the chosen material the production costs are low. Simulations and measurements have been performed taking into account two antennas working as a MIMO configuration. Both numerical and measurement results show good performances in terms of return loss, coupling and gain.

Abstract
In this study, a low profile wideband 3D antenna for roof-top LTE vehicular applications is presented. The structure consists of folded metal sheets welded together building a geometry that allows covering two LTE bands: 700MHz-960MHz, 1700MHz-2700MHz. The shape and the size of the antenna allow to fit it under the shark-fin case, and thanks to the chosen material the production costs are low. Simulations and measurements have been performed taking into account two antennas working as a MIMO configuration. Both numerical and measurement results show good performances in terms of return loss, coupling and gain.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
