Antenna arrangement and communication device

An antenna arrangement for a communication device, the antenna arrangement comprising:

• a substrate having a top surface and a bottom surface;
• a top conductive patch arranged on the top surface, the top conductive patch comprising a first section and a second section adjoining the first section;
• a bottom conductive patch arranged on the bottom surface opposite to the top conductive patch;
• and
• one or more feed circuits configured to carry a radio frequency (RF) signal to or from the top conductive patch,
• wherein the top conductive patch comprises a plurality of coupling points at which the top conductive patch is coupled to the one or more feed circuits, the plurality of coupling points comprising:
• a first coupling point located in the first section and a second coupling point located in the second section such that the RF signal has a first phase at the first coupling point and a second phase at the second coupling point, and
• a third coupling point located in the first section and a fourth coupling point located in the second section such that the RF signal has a third phase at the third coupling point and a fourth phase at the fourth coupling point, and
• wherein a first slot extends in the top conductive patch between the first coupling point and the second coupling point and a second slot extends in the top conductive patch between the third coupling point and the fourth coupling point.
