PLANAR ANTENNA FOR MOBILE RADIOPHONE (ALTERNATIVES) Russian patent published in 2002 - IPC

FIELD: antenna-feeder engineering; radiophone antennas. SUBSTANCE: both alternatives of antenna have top and bottom rectangular electricity-conducting plates with insulating plate in- between; they are assembled to form pack for external connections. First alternative of antenna has two pairs of substrate-disposed electricity- conducting strips diverging in opposite directions and connected to longitudinal sides of bottom electricity-conducting plate residing on same substrate. In second alternative top and bottom electricity-conducting plates are interconnected on one lateral side; connected to respective points on longitudinal sides of top electricity-conducting plate disposed on insulating plate are electricity-conducting strips of first pair disposed on same plate and positioned in first longitudinal direction (in direction away from mentioned connection of electricity-conducting plates); connected to similarly arranged points on longitudinal sides of bottom electricity-conducting plate residing on supporting insulating substrate are electricity-conducting strips of second pair disposed on same substrate and positioned in longitudinal direction opposing first one. EFFECT: provision for suppressing user's head oriented radiation. 4 cl, 4 dwg
