Abstract
An automobile antenna apparatus according to the present invention includes an antenna control section for electronically and variably controlling (beam-steering or beam-scanning) an emitting-beam pattern of each of antennas mounted on an automobile, based on high-precision positional information of the automobile, to optimize a function of using an electric wave for vehicle (for broadcast wave reception, mobile communications, positioning, obstruction detection and the like).
Claims11
An automobile antenna apparatus comprises an antenna control section including:
- a first means for electronically and variably controlling an emitting-beam pattern of each of antennas mounted on an automobile, based on high-precision positional information of the automobile;
- and
- a second means for optimizing a function of using an electric wave for vehicle based on the electrically and variably controlling of the emitting-beam pattern.
An automobile antenna apparatus comprises a smart antenna, the smart antenna including:
- a slot antenna having a slot space as a main element, the slot space being surrounded with a first region in which a metal film covers a defogger formed on a window of an automobile and a second region formed of a metal portion of a car body including a window frame of the automobile;
- and
- an integrated multiband antenna having a plurality of antenna elements of thin-film conductive pieces which are arranged such that at least some of the antenna elements are inserted into the slot space of the slot antenna.
An automobile antenna apparatus comprises an anti-collision EHF radar mounted at least on a front of an automobile and having a beam scanning function capable of emitting a beam within a predetermined angle range.
An automobile antenna apparatus comprising:
- an anti-collision EHF radar mounted at least on a front of an automobile and having a beam scanning function capable of emitting a beam within a predetermined angle range;
- automobile position detection means for correctly detecting automobile position information by a composite high-precision positioning system of DGPS and dead reckoning navigation;
- and
- means for automatically setting a target detection range by the automobile position information detected by the automobile position detection means and the beam scanning function of the anti-collision EHF radar.
