Abstract

An antenna assembly comprising: an antenna; a circuit unit; and a device cover for connection between the antenna and the circuit unit to electrically couple the antenna to the circuit unit.

Claims

1. An antenna assembly comprising:

a cover for a shield, said cover comprising an antenna having a radiating region, and being pressure-attachable to a lower shield member;

said lower shield member comprising a circuit unit, and

a pressure-connecting means which electrically couples the radiating region of said antenna to said circuit unit when said cover is pressure-attached to said lower shield member.

2. An antenna assembly according to claim 1 in which said pressure-connecting means is resiliently-deformable.

3. An antenna assembly according to claim 1 in which said pressure-connecting means is a pressure-biased spring pin.

4. An antenna assembly according to claim 1 in which said cover and said lower shield member are releasable-attached to each other.

5. An antenna assembly according to claim 4 in which said cover and said lower shield member are frictionally attached to each other.

6. An antenna assembly according to claim 1 in which said antenna and said cover are discrete parts which are fixedly attached to each other as a unit.

7. An antenna assembly according to claim 1 in which said antenna also comprises a ground region which is pressure-connected to ground via said lower shield member when the cover is pressured-attached to the lower shield member.

8. An antenna assembly according to claim 7 in which the cover comprising the antenna is provided with resiliently deformable conductive flanges which frictionally-engage a peripheral conductive shield wall on the lower shield member, connected to ground, to ground the ground region of the antenna when the cover and the lower shield member are pressure-attached to each other.

9. An antenna assembly according to claim 8 in which said conductive shield wall provides a shield for the circuit unit against electromagnetic radiation.
