Zylindrische Antennenverkleidungen für Sektorantennen des Mobilfunks bei weitestgehend voneinander unabhängiger Dimensionierung nach mechanischen und elektrischen Kriterien, dadurch gekennzeichnet, dass der zylindrische oder polygone Querschnitt der Antennenumhausung eine dreischichtige Struktur aufweist, wobei im elektrisch wirksamen Bereich, hinter dem sich die Antennen (5) befinden, der Abstand dA zwischen der inneren Schicht (innerer Zylinder) (1) und der äußeren Schicht (äußerer Zylinder) (2) der Antennenumhausung so gewählt ist, dass Reflexionen an der einen Schicht durch Reflexionen an der anderen Schicht weitestgehend kompensiert werden.1. Cylindrical antenna cladding for sector antennas of mobile radio with largely independent dimensioning according to mechanical and electrical criteria, characterized in that the cylindrical or polygonal cross section of the antenna housing has a three-layer structure, with the electrically effective area behind which the antennas ( 5 ) are located , the distance d A between the inner layer (inner cylinder) ( 1 ) and the outer layer (outer cylinder) ( 2 ) of the antenna housing is chosen so that reflections on one layer are largely compensated for by reflections on the other layer. 2. Antennenverkleidung nach Anspruch 1 dadurch gekennzeichnet, dass die beiden äußeren Schichten (1, 2) der Dicken di und da etwa gleiche elektrische Dicken di/λi ≈ da/λa, vorzugsweise d/λ ≦ 0,05, haben und ihr elektrischer Abstand dA/λA ≦ 0,3 beträgt.2. Antenna cladding according to claim 1, characterized in that the two outer layers ( 1 , 2 ) of the thicknesses d i and d a have approximately the same electrical thicknesses d i / λ i ≈ d a / λ a , preferably d / λ ≦ 0.05 , and their electrical distance d A / λ A ≦ 0.3. 3. Antennenverkleidung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die dreischichtige Querschnittsstruktur dadurch realisiert wird, dass ein nach mechanischen Belastungen dimensionierter tragender Zylinder (7) durch einen konzentrisch angeordneten Kompensationszylinder (6) ergänzt wird, dessen Durchmesser so gewählt ist, dass der elektrische Abstand zwischen beiden Zylindern ≦ 0,3 beträgt. 3. Antenna cladding according to claim 1 or 2, characterized in that the three-layer cross-sectional structure is realized in that a supporting cylinder ( 7 ) dimensioned according to mechanical loads is supplemented by a concentrically arranged compensation cylinder ( 6 ), the diameter of which is selected such that the electrical distance between the two cylinders is ≦ 0.3. 4. Antennenverkleidung nach Anspruch 3, dadurch gekennzeichnet, dass der Kompensationszylinder (6) innerhalb oder außerhalb des tragenden Zylinders (7) angeordnet ist.4. radome according to claim 3, characterized in that the compensating cylinder (6) is arranged inside or outside of the supporting cylinder (7). 5. Antennenverkleidung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass tragende Zylinder (7) und der Kompensationszylinder (6) durch Abstandselemente in ihrer Lage zueinander fixiert sind, wobei als Abstandselemente u. a. sowohl waagerechte Scheiben oder Streben als auch radial angeordnete senkrechte Flächen und dgl. dienen können.5. Antenna cladding according to one of claims 1 to 4, characterized in that the supporting cylinder ( 7 ) and the compensation cylinder ( 6 ) are fixed in their position with respect to one another by spacing elements, wherein spacing elements include both horizontal disks or struts and radially arranged vertical surfaces and the like. 6. Antennenverkleidung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die dreischichtige Struktur dadurch realisiert wird, dass die drei Schichten fest miteinander verbunden sind, so dass eine Sandwichstruktur bestehend aus zwei Deckschichten (1, 2) und der dazwischen liegenden Kernschicht (3) vorhanden ist.6. Antenna cladding according to claim 1 or 2, characterized in that the three-layer structure is realized in that the three layers are firmly connected to one another, so that a sandwich structure consisting of two cover layers ( 1 , 2 ) and the core layer ( 3 ) lying in between is available.
