    jede Zelle (205) ein erstes Antennenelement (205a) aufweist, das in der ersten leitenden Schicht (M1) ausgebildet ist, und ein zweites Antennenelement (205b) aufweist, das in der dritten leitenden Schicht (M3) ausgebildet ist, wobei die erste leitende Schicht (M1) eine diskontinuierliche Schicht ist, so dass die ersten Antennenelemente (205a) der verschiedenen Zellen (205) voneinander isoliert sind, und die dritte leitende Schicht (M3) eine diskontinuierliche Schicht ist, so dass die zweiten Antennenelemente (205b) der verschiedenen Zellen (205) voneinander isoliert sind;
    in jeder Zelle des ersten Typs (205-I) das erste Antennenelement (205a) mit dem zweiten Antennenelement (205b) durch einen leitenden Durchgang (211) verbunden ist, der durch eine in der zweiten leitenden Schicht (M2) ausgebildete Öffnung (213) verläuft, wobei der Durchgang (211) und die Öffnung (213) so angeordnet sind, dass der Durchgang nicht in Kontakt mit der zweiten leitenden Schicht (M2) steht; und
    in jeder Zelle des zweiten Typs (205-II) das erste Antennenelement (205a) nicht mit dem zweiten Antennenelement (205b) verbunden ist.
  2. Sende-Anordnung (203) nach Anspruch 1, wobei in jeder Zelle (205) das zweite Antennenelement (205b) zumindest teilweise dem ersten Antennenelement (205a) gegenüberliegt.
  3. Sende-Anordnung (203) nach Anspruch 1 oder 2, wobei in jeder Zelle des zweiten Typs (205-II) das erste Antennenelement (205a) mit dem zweiten Antennenelement (205b) durch einen Spalt (215) gekoppelt ist, der in der zweiten leitenden Schicht (M2) ausgebildet ist und zumindest teilweise dem ersten (205a) und dem zweiten (205b) Antennenelement gegenüberliegt.
  4. Sende-Anordnung (203) nach einem der Ansprüche 1 bis 3, die N verschiedene Zellkonfigurationen (UC1, UC2, UC3, UC4, UC5, UC6, UC7, UC8) aufweist, wobei N eine ganze Zahl größer oder gleich 2 ist, wobei die Anordnung eine Vielzahl von Zellen (205) jeder Konfiguration umfasst.
  5. Sende-Anordnung (203) nach Anspruch 4, wobei die N Zellkonfigurationen so ausgewählt sind, dass die N Phasenverschiebungswerte, die jeweils von den Zellen der N Konfigurationen eingeführt werden, in der Größenordnung von 0°, 360°/N, 2*360°/N, ... (N-1)*360°/N liegen.
  6. Sende-Anordnung (203) nach Anspruch 5, wobei N gleich 8 ist.
  7. Sende-Anordnung (203) nach einem der Ansprüche 1 bis 6, wobei in jeder Zelle das erste Antennenelement (205a) durch ein kontinuierliches leitendes Muster und das zweite Antennenelement (205b) durch ein kontinuierliches leitendes Muster gebildet ist.
  8. Sende-Anordnung (203) nach einem der Ansprüche 1 bis 7, wobei in jeder Zelle das erste Antennenelement (205a) einen Oberflächenbereich von mehr als 20 % des Oberflächenbereichs der Zelle einnimmt und das zweite Antennenelement (205b) einen Oberflächenbereich von mehr als 20 % des Oberflächenbereichs der Zelle einnimmt.
  9. Sende-Anordnungs-Antenne mit der Sende-Anordnung (203) nach einem der Ansprüche 1 bis 8 und mindestens einer Primärquelle (101), die so konfiguriert ist, dass sie eine Oberfläche der Anordnung (203) bestrahlt.
  10. Antenne nach Anspruch 9, die in der Lage ist, bei einer Frequenz im Bereich von 1 bis 300 GHz zu funktionieren.
