FIELD: physics.
SUBSTANCE: antenna unit has a housing, a base lying at one end of the housing, and an antenna in form of a printed-circuit board which passes through the base into the housing, wherein the end of the antenna lies outside the antenna unit and a sealing compound, lying inside the base; the antenna passes through the sealing compound which encapsulates the antenna to provide airtight interfacing of the antenna and the base. The unit has an elastic component lying at the base and connected to the antenna, which has a flexible loop lying near the elastic component.
EFFECT: providing airtight interfacing of the antenna and the base.
