Claims5
An antenna device;
- comprising:
- an antenna module, adapted to receive a radio signal;
- an antenna case, having a top case formed with a first engagement part and a bottom case formed with a second engagement part adapted to be engaged with the first engagement part to couple the bottom case to the top case to accommodate the antenna module therein;
- and
- a packing member, held between the antenna module and the bottom case so as to cover at least a part of the antenna module;
- wherein the packing member is compressed such that elastic force of the packing member reinforces engagement between the top case and the bottom case when the first engagement part and the second engagement part are engaged with each other.
