Title: Antenna system
Inventor: IWAMOTO MAKOTO
IPC: H01Q19/12
Filed: 1984-11-27
Abstract: PURPOSE:To protect the antenna system against closing by providing a vent tube connecting an air-tight case and a space and providing a pressure regulating valve in a flowing path of the vent tube. CONSTITUTION:When the antenna system is closed and a pressure Pi of the air-tight case 13 is lower than a pressure Pc of the space 16, the pressure regulating valve 14 is operated and the air in the space part 16 flows to the air-tight case 13 via the vent tube 15. Conversely, when the Pi is higher than the Pc, the air of the air-tight case 13 flows to the space part 16 by the operation of the regulating valve 14. Since the air in the space part 16 and open air are conducted through a gap of a bonding face between a protection cover 11 and a beam 12, the pressure is nearly equal to an open air pressure. Thus, the pressuer Pi of the air-tight case 13 is kept within the operating pressure range of the regulating valve 14. Thus, the antenna system is protected from the closing.
