Abstract
The present invention relates to an antenna arrangement on a circuit board (10) extending along a length direction, L, and a width direction, W, the width direction being orthogonal to the length direction. The antenna arrangement comprising: a cell-band antenna (20); a ground plane (30) associated with the cell-band antenna; and a slit antenna (40) arranged in a slit antenna portion (32) of the ground plane, the slit antenna comprising a slit (42) in the ground plane, the slit having in the width direction a slit extension extending from an in the length direction extending edge (34) of the ground plane, the slit extension being 50-95% of an in the width direction extending total width of the slit antenna portion.

An antenna arrangement on a circuit board extending along a length direction and a width direction the width direction being orthogonal to the length direction, the antenna arrangement comprising:
- a cell-band antenna;
- a ground plane associated with the cell-band antenna and the ground plane acting as a counterpoise to the cell-band antenna;
- and
- a slit antenna arranged in a slit antenna portion of the ground plane, the slit antenna comprising a slit in the ground plane, the slit having, in the width direction, a slit extension extending from, in the length direction, an extending edge of the ground plane, the slit extension being 50-95% of an in the width direction extending total width of the slit antenna portion, wherein the ground plane comprises an in the length direction and in the width direction extending mid portion, the mid portion is arranged between the cell-band antenna and the slit antenna, the mid portion having in the width direction a mid portion extension extending from the edge of the ground plane, the mid portion extension being smaller than the slit extension.
