Patent ID: 8816927

Claim:
An electronic apparatus comprising: a housing having a conductor portion; and an antenna unit fixed to the housing and connected electrically to the conductor portion, the antenna unit comprising: a substrate; a grounding conductor portion formed on one main face of the substrate; an antenna conductor portion formed on the main face of the substrate; and a reflective conductor portion formed on the main face of the substrate, wherein the antenna conductor portion and the reflective conductor portion are spaced from each other, and the reflective conductor portion extends in an extension direction of the antenna conductor portion and has a length equal to or more than the length of the antenna conductor portion, the conductor portion has a protrusion capable of supporting the antenna unit in a predetermined posture, the substrate of the antenna unit is fixed to the protrusion so that one of the main faces of the substrate opposes the conductor portion of the housing with a predetermined distance therebetween and is arranged at a position to overlap the conductor portion of the housing when viewed in the thickness direction of the substrate, the grounding conductor portion and the reflective conductor portion are grounded via the protrusion and the conductive portion of the housing, and in a practical use state of the electronic apparatus, the antenna unit is fixed to the protrusion of the conductor portion in a posture so that the reflective conductor portion is positioned vertically below the antenna conductor portion.
