Definitions
- the dipole antenna 1 and the compact disc 2 are inserted in a box-like housing.
- the housing comprises a cover part 3, a bottom part 4 and sides 5 connecting the cover part and the bottom part with each other.
- the compact disc 2 is attached to the bottom part 4, inside the housing, such that the reflecting groove- side of the compact disc is directed towards the cover part of the housing.
- the compact disc can be attached to the bottom part of the housing e.g. by gluing or using an appropriate fastener.
