Patent ID: 7688266

Claim:
An antenna module comprising: a substrate; a ground element disposed on the substrate; a first antenna element disposed on the substrate and configured to transmit a radio wave having a first polarization direction; a second antenna element disposed on the substrate and configured to transmit a radio wave having a second polarization direction; a first feeding point disposed in the first antenna element on a ground element side; and a second feeding point disposed in the second antenna element on a ground element side, wherein: the first polarization direction is nonparallel to the second polarization direction; the ground element is configured so that a spacing between a perimeter of the ground element and the first antenna element has a minimum located proximal to the first feeding point and the spacing increases in a direction away from the second antenna element; and the ground element is configured so that a spacing between the perimeter of the ground element and the second antenna element has a minimum located proximal to the second feeding point and the spacing increases in a direction away from the first antenna element.
