Claim 0:
1. An antenna structure comprising:
a substrate having opposite first surface and second surface, and comprising liquid crystal polymer material;
a plurality of reflective plates arranged in an array on the first surface of the substrate;
a first grounding plate arranged on the second surface of the substrate and overlapped with the reflective plates in the normal direction of the substrate;
a first radiating member arranged on the second surface of the substrate and not overlapped with the reflective plates in the normal direction of the substrate,
the first radiating member having an open slot defined by a first radiating branch and a second radiating branch, and generates at least two different operating frequency bands, wherein a length of the first radiating branch is from 0.23λ1 to 0.25λ1, and a length of the second radiating branch is from 0.23λ2 to 0.25λ2, where λ1 and λ2 are wavelengths of a first resonance frequency and a second resonance frequency respectively corresponding to the two operating frequency bands; and
a plurality of conductive vias penetrating through the substrate and respectively connecting the reflective plates on the first surface and the first grounding plate on the second surface of the substrate.
