1. An antenna structure disposed on a dielectric substrate having a first surface and a second surface opposite to the first surface, wherein the antenna structure comprises:
a grounding metal sub-structure disposed at the first surface;
an electromagnetic wave transmitting sub-structure disposed at the second surface and extended along a first direction, wherein the electromagnetic wave transmitting sub-structure comprises a signal input part, and an input signal received from the signal input part is correspondingly emitted from the electromagnetic wave transmitting sub-structure to outward circumstances as an emitted electromagnetic wave;
an electromagnetic wave receiving sub-structure disposed at the second surface and extended along the first direction, wherein the electromagnetic wave receiving sub-structure comprises a signal output part, and an incoming electromagnetic wave received by the electromagnetic wave receiving sub-structure is converted to an output signal and outputted from the signal output part; and
an isolation metal sub-structure disposed at the second surface and between the electromagnetic wave transmitting sub-structure and the electromagnetic wave receiving sub-structure, wherein the isolation metal sub-structure is extended along the first direction and comprises a cross-type metal block and a plurality of straight-line-type metal blocks separated from each other,
wherein, the cross-type metal block is disposed between the signal input part and the signal output part, the cross-type metal block and each of the straight-line-type metal blocks comprises a plurality of metal holes, and each of the metal holes is connected to the grounding metal sub-structure.
