Abstract

The present invention relates generally to a receiver antenna construction for a mobil communication unit adapted to be worn by the operator on the head. The antenna of the receiver is initially orientated in an inclined position in relation to the geometrical vertical line of the head in order to be able to receive the optimal value of the field strength deriving normal work positions of the head of the operator.

Claims

1. In combination with a portable radio receiver, a housing for enclosing said receiver, a headband for supporting said housing along one side of the head of a user, said headband and housing defining a plane of symmetry coincident with the lateral plane of symmetry of the head of the user, an antenna integrally mounted in said housing with said receiver, said antenna comprising a coil having a longitudinal axis, said coil being fixedly mounted with respect to said receiver at a rearwardly inclined angle of between 15°

- 45°

with respect to the plane of symmetry of the headband and receiver when worn in the normally geometric vertical position on the head.
