INTEGRATED DUAL BAND ANTENNA AND METHOD FOR AERONAUTICAL SATELLITE COMMUNICATION

摘要

An antenna device having a dual band antenna for the frequency ranges of the L-band (1.5 GHz – 1.7 GHz) and Ku-band (10.7 GHz – 14.5 GHz), particularly for aeronautical applications, comprising a level antenna field (100) of Ku-band antenna elements, which are connected to each other by a feed network (101), and at least one L-band antenna element (105), is proposed, wherein the feed network is provided with an electrically conductive, particularly metal, shielding (103) such that the Ku-band antenna elements are not shielded and an incident electromagnetic wave can be received without interference, and the at least one L-band antenna element is arranged in the direction of incidence over the Ku-band antenna field and designed such that it comprises a metal structure, which in the direction of incidence has one or more openings, so as to ensure that the Ku-band antenna elements are not completely covered by the metal structure of the at least one L-band antenna element in the direction of incidence.
