  • unit structure 10A is configured to reflect radio waves in the band of approximately 29.5 GHz to 32.5 GHz when connection portion 71 to connection portion 74 is in a short-circuited state.
  • the unit structure 10A can transmit or reflect radio waves in the band from about 29.5 GHz to 32.5 GHz by switching the first resonator 51 and the second resonator 52 between a short-circuited state and an open state.
  • the second embodiment is configured to be able to change the number of resonators included in the unit structure. This allows the second embodiment to switch between reflection and transmission of the unit structure.

Abstract

Cette plaque de commande d'ondes radio comprend une pluralité de structures unitaires agencées dans une première direction plane. Chaque structure unitaire comprend : une pluralité de résonateurs qui s'étendent dans la première direction plane; des conducteurs de couplage qui ajustent un coefficient de couplage entre la pluralité de résonateurs; et des parties de connexion qui changent la structure conformément à une matrice de couplage des structures unitaires.
