    • The present invention relates to a planar antenna (1) for excitation of the TE01-mode of an electromagnetic wave and adapted to be arranged in a waveguide tube (2). The planar antenna comprises a substrate (6) of dielectric material having a first surface (7) intended to face towards a filling good surface and a second surface (8) facing in an opposite direction. A first group (9) of a plurality of dipole arms (10) is arranged on the first surface (7) or the second surface (8) on a perimeter of a circle with a predetermined radius. A second group (11) of a plurality of dipole arms (12) is arranged on the first surface (7) or the second surface (8) on the perimeter of the circle with the predetermined radius. The dipole arms (10) of the first group (9) extend in a first direction and the dipole arms (12) of the second group (11) extend in a direction opposite the first direction. Furthermore, the present invention relates to an antenna system comprising a cylindrical waveguide tube (2) having a bottom plate (3) and a tube portion (4) and a planar antenna (1) as mentioned above.
    • 本发明涉及一种用于激发电磁波的TE01模式并适于布置在波导管(2)中的平面天线(1)。 平面天线包括电介质材料的基底(6),其具有面向着填充良好表面的第一表面(7)和面向相反方向的第二表面(8)。 多个偶极臂(10)的第一组(9)布置在具有预定半径的圆周上的第一表面(7)或第二表面(8)上。 多个偶极臂(12)的第二组(11)布置在具有预定半径的圆周上的第一表面(7)或第二表面(8)上。 第一组(9)的偶极臂(10)沿第一方向延伸,并且第二组(11)的偶极臂(12)沿与第一方向相反的方向延伸。 此外,本发明涉及一种天线系统,其包括如上所述的具有底板(3)和管部分(4)的圆柱形波导管(2)和平面天线(1)。
