Abstract
An antenna arrangement is provided that includes a patch radiator, a feed arrangement, for the patch radiator and a cavity for the feed arrangement. The feed arrangement includes a slot in a conductive layer located between the patch radiator and the cavity.
Claims19
An antenna arrangement comprising:
- a patch radiator;
- a feed arrangement, for the patch radiator;
- and
- a cavity for the feed arrangement,
- wherein the feed arrangement comprises an elongate slot, forming a closed loop, in a conductive layer located between the patch radiator and the cavity, and wherein the slot is sinuous comprising multiple bends of different handedness.
2 more elements
A base station comprising an array of antenna arrangements, wherein
- at least one of the array or antenna arrangements comprises:
- a patch radiator;
- a feed arrangement, for the patch radiator;
- and
- a cavity for the feed arrangement,
- wherein the feed arrangement comprises an elongate slot, forming a closed loop, in a conductive layer located between the patch radiator and the cavity, and wherein the slot is sinuous comprising multiple bends of different handedness.
3 more elements
An antenna arrangement comprising:
- a patch radiator;
- a feed arrangement for the patch radiator;
- and
- a cavity for the feed arrangement,
- wherein the feed arrangement comprises a slot in a conductive layer located between the patch radiator and the cavity,
- wherein the feed arrangement comprises (i) a first pair of feed conductors, of different lengths, that extend over different portions of the slot, and are aligned and oriented in a first direction and (ii) a second pair of feed conductors, of different lengths, that extend over different portions of the slot, and are aligned and oriented in a second direction that is orthogonal to the first direction,
- wherein the feed arrangement comprises a balanced feed arrangement, and
- wherein at an operational frequency band, conductive interconnects to the first pair of feed conductors introduce a 180° phase difference between the first pair of feed conductors, which are connected as open-circuit, and conductive interconnects to the second pair of feed conductors introduce a 180° phase difference between the second pair of feed conductors.
