Abstract (en)

[origin: WO2009108097A1] There is disclosed an antenna element, including at least one antenna patch and a feeding arrangement which comprises: a ground plane including: a first aperture slot and a second aperture slot, where said aperture slots cross each other perpendicularly; a feeding plane including: a first antenna port for feeding microwave energy via a first feeding junction into a first pair of feed lines which extend in parallel along said first aperture slot, on each side thereof; a second antenna port for feeding microwave energy via a second feeding junction into a second pair of feed lines which extend in parallel along said second aperture slot, on each side thereof; and where said feed lines cross each other in at least one point, at a mutual distance. Said feeding arrangement is furthermore irregularly configured for compensating for an imbalance caused by said crossing of said feed lines.
