Title:
ON-BOARD ANTENNA
Document Type and Number:
WIPO Patent Application WO/2013/161520
Kind Code:
A1
Abstract:
Provided is an on-board antenna by which the requisite waterproofness can be ensured even with an antenna base being made of resin, and which is advantageous in lowering costs and reducing weight. An antenna base (21) made of resin has a concave section (211) on a lower surface. A hole (212) is provided to an upper surface of the concave section (211). An antenna case (31) is placed from above onto the antenna base (21), with a pad (22) interposed therebetween. A sealing member (23) is attached to the lower surface of the antenna base (21) so as to surround the concave section (211) of the antenna base (21). A circuit board (24) is housed in the concave section (211) of the antenna base (21). A guide body section (335a) for guiding a terminal of a coil element (33) extends within the hole (212) of the concave section (211) of the antenna base (21). An O-ring (34) fitted to a concave section (335b) of the guide body section (335a) is sandwiched between a lateral surface of the guide body section (335a) and the inner surface of the hole (212).
