Abstract
A method and an arrangement for testing a radio device without radiation losses are provided. The arrangement comprises a waveguide closed at both its ends and comprising a holder arranged to hold the radio device at least partly inside the waveguide in such a manner that the radiating part of the radio device remaining outside the waveguide is entirely inside the holder. The arrangement also comprises at least one coupling inside the waveguide for transmission and reception of a radio-frequency signal.
Claims21
An arrangement for testing a radio device comprising:
- a waveguide closed at both of its ends;
- and
- comprising a holder arranged to hold the radio device partly inside the waveguide in such a manner that at least a portion of the radiating part of the radio device remains outside the waveguide, the at least a portion of the radiating part of the radio device remaining outside the waveguide being entirely inside the holder, wherein the waveguide comprises:
- one or more ridges extending along a longitudinal axis of the waveguide, the end of at least one ridge facing the holder being bevelled;
- and
- one coupling inside the waveguide for transmission and reception of a radio-frequency signal by the use of a wideband mode of propagation;
- wherein the end of the waveguide on the side of the holder comprises one or more pegs made from a conductive substance and fastened to the inner surface of the waveguide.
A method of testing a radio device, wherein the radio device to be tested is mounted by means of a holder such that the radio device is held partly inside a waveguide closed at both of its ends, the method comprising:
- generating a wideband mode of propagation in the waveguide by means of at least one ridge extending along a longitudinal axis of the waveguide, the end of the at least one ridge facing the holder being bevelled;
- and
- transmitting and receiving radio-frequency signals by using the wideband mode of propagation between the radio device and a coupling installed in the waveguide, at least a portion of the radiating part of the radio device remaining outside the waveguide, the at least a portion of the radiating part of the radio device remaining outside the waveguide being entirely inside the holder;
- wherein one or more pegs made from a conductive material are fastened to the inner surface of the waveguide at the end of the waveguide on the side of the holder.
