  • Patent number: 10151783
    Abstract: An apparatus and a method for determining an antenna characteristic of an antenna under test in free space is disclosed. Measurement results of a transmitted power of a measurement signal transmitted between the reference antenna and an antenna under test are detected, wherein detecting takes place in the frequency domain. The detected measurement results are transformed into the time domain and a time-domain filter is applied to the measurement results converted into the time domain. A filter width of the time-domain filter is determined in dependence on a spatial distance between the reference antenna and the antenna under test. Measurement result portions that result due to a multipath propagation of the measurement signal between the reference antenna and the antenna under test are reduced or removed.

  • Publication number: 20180236303
    Abstract: The invention relates to a golf ball (1), which has at least one transmitting and receiving antenna (10) and a position determination unit (11), which has a communicative connection to the transmitting and receiving antenna (10) and is designed to receive GPS data, which specify the position of the golf ball (1). Furthermore, the golf ball has a communication unit (12), which has a communicative connection to the transmitting and receiving antenna (10) and is designed to transmit radio data, in particular the position of the golf ball (1). In addition, the golf ball has at least one charging coil (14), which is connected to an energy store (13) and is designed to charge the energy store (13) by means of inductive energy transmission. Moreover, the invention relates to a method for locating an object, in particular a ball-like object, for example, a golf ball, and a transmitting and receiving antenna for use in such a ball-like object.
