ANTENNA WITH SUBSTRATE AND CONDUCTOR TRACK STRUCTURE |
摘要 |
<p>An antenna (1) is described with a dielectric or permeable substrate (10) and at least one resonant conductor track structure (20) which is provided in particular for use in the high-frequency and microwave ranges and which is characterized in that the substrate (10) comprises at least one cavity (30). The cavity is preferably provided in a main surface of the substrate such that the latter has substantially the shape of a U-profile. This cavity not only enhances the radiation efficiency, but it also considerably reduces the total weight of the antenna. Further advantages of the antenna are that it offers a high degree of miniaturization as well as the possibility of surface mounting (SMD) on, for example, a printed circuit board (PCB).</p> |
