Antenna arrangement and a radio apparatus including the antenna arrangement
First Claim
1. An antenna arrangement comprising:
- a ground plane anda planar antenna element mounted spaced from and parallel to the ground plane,wherein a slot is provided in the ground plane, the slot being coextensive with an edge portion of the ground plane and having a first end opening into the edge portion of the ground plane and a second closed end, an antenna feed coupled to the slot at a location intermediate the first and second ends, and wherein the planar antenna element is connected by an electrically conductive wall to the edge portion of the ground plane, the wall being co-extensive with the slot.

Abstract
An antenna arrangement comprises a ground plane (14) and a planar antenna element (30) mounted spaced from and parallel to the ground plane. An open-ended slot (16) is provided in the ground plane (14), the slot being coextensive with an edge portion of the ground plane and having a first end (18) opening into the edge portion of the ground plane and a second closed end (20). An antenna feed (22) is coupled to the slot at a location intermediate the first and second ends. The planar antenna element is connected by an electrically conductive wall (28) to the edge portion of the ground plane, the wall (28) being coextensive with the slot (16). The combination of the slot shape, slot location and the wall serves to increase the bandwidth of the antenna arrangement.
