Antenna structure having patch elements
First Claim
Patent Images
1. An antenna structure, comprising:
- a plurality of serially fed antenna columns which are situated in an elevation direction and which operate in an elevation plane;
a feed line; and
a plurality of serially fed patch elements, at least one of the patch elements having a slot coupling to a continuation of the feed line for use in the antenna columns and influencing a radiation of the at least one patch element, the continuation of the feed line varying beam formation and side lobe suppression in the elevation plane of the antenna columns;
wherein the patch elements are spaced apart from each other by a distance and are electrically isolated from each other.

10. A radar sensor, comprising:
-
a plurality of serially fed patch elements, a serial feed path forming an antenna column within a group antenna, at least one of the patch elements having a slot coupling to a continuation of a feed line for use in the antenna column and influencing a radiation of the at least one patch element, the continuation of the feed line varying beam formation and side lobe suppression in the elevation plane of the antenna column; wherein the patch elements are spaced apart from each other by a distance and are electrically isolated from each other, and wherein the group antenna includes an antenna structure that includes a plurality of serially fed antenna columns which are situated in an elevation direction and which operate in an elevation plane, the feed line, and the plurality of serially fed patch elements. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
