BROADBAND ANTENNA SYSTEM Russian patent published in 2006 - IPC H01Q1/32 

FIELD: antenna engineering; radio communication systems mounted on mobile carriers.

SUBSTANCE: antenna system that uses vehicle body as radiating member and has first and second current conductors connected to respective input terminals of first two-port V₁ whose output terminals function as input ones for first transceiver E₁ is provided in addition with n (n ≥ 1) distributed-parameter capacitors C₂(1) - C₂(n). Each capacitor is inserted between vehicle body and first current conductor of each of n two-ports V₁ through V_n; second conductor connects respective input terminals of each two-port to counterpoise insulated from vehicle body. Output terminals (n - 1) of two-ports function as input ones for respective (n --1) transceivers.

EFFECT: provision for using vehicle body as radiating member for several transceivers.
