COAXIAL RADIATING CABLE Russian patent published in 2002 - IPC

FIELD: radio engineering; contactless communications; antenna radiators. SUBSTANCE: radiating cable has internal conductor inside insulating layer and external conductor with holes. Novelty is that internal conductor has radial conducting inserts placed between internal and external conductors coaxially relative to holes. Cross-sectional areas of conducting inserts are smaller than areas of respective holes. Shapes of conducting-insert sections and their orientation follow those of respective holes. In addition radial conducting inserts may be provided with conducting nozzles which contact these inserts and are free to move longitudinally along them. EFFECT: reduced standing-wave ratio; enhanced radiation level and uniformity. 2 cl, 2 dwg
