Summary:The invention relates to an antenna (10, 10 ') for a high-frequency-based measuring device (1) for determining a dielectric value of a medium (2). In order to transmit and/or receive corresponding high-frequency signals (SHF, EHF), the antenna (10, 10 ') is based on a high-frequency waveguide (100). The high-frequency signals (SHF, EHF) are coupled in or out by means of a coaxial conductor (101), which extends orthogonally through the axis (a) of the high-frequency waveguide (100) for this purpose. In this case, a conductor end (1012) of the coaxial conductor (101) extends beyond the high-frequency waveguide (100) in a protruding (l) manner, such that the coaxial conductor (101) creates a defined capacitance (C) in this region. In this way, the coaxial conductor (101) is optimally matched to the high-frequency waveguide (100) without having to integrate additional electrical components for this purpose. This results in a high-efficiency high-frequency antenna (10, 10 ') which is easy to produce due to the few
