A planar inverted F antenna structure includes an insulating substrate having a main face, a ground plane conductor on the main face of the substrate, the ground plane conductor having a straight edge, and an antenna element on the main face of the substrate. The antenna element includes a feed portion, a ground return portion, and a radiative arm projecting from the feed portion and extending beside the straight edge of the ground plane conductor. A first edge of the antenna arm is a straight edge that is located between a second edge of the antenna arm and the straight edge of the ground plane conductor and is spaced from the straight edge of the ground plane conductor. The first edge of the antenna arm is inclined to the straight edge of the ground plane conductor. |
