Abstract

A coupling-type grating antenna includes a substrate having opposing top surface and bottom surface, a monopole antenna element formed on the top surface of the substrate for transmitting a first current and having a feed point and a radiator and a grating conductor respectively extended from the feed point, and a coupling grating body formed on the bottom surface of the substrate opposite to the monopole antenna element for transmitting a second current. Further, the transmitting direction of the first current in the monopole antenna element is reversed to the transmitting direction of the second current in the coupling grating body.

First claim

What is claimed is:

1 . A coupling-type grating antenna, comprising:
a substrate comprising a top surface and an opposing bottom surface; a monopole antenna element formed on said top surface of said substrate and adapted for transmitting a first current, said monopole antenna comprising a feed point, and a radiator and a grating conductor respectively extended from said feed point; and a coupling grating body formed on said bottom surface of said substrate opposite to said monopole antenna element and adapted for transmitting a second current; wherein the transmitting direction of said first current in said radiator and said grating conductor is reversed to the transmitting direction of said second current in said coupling grating body.

2 . The coupling-type grating antenna as claimed in claim 1 , wherein said radiator comprises a transverse radiator segment having one end thereof connected to said feed point, and a longitudinal radiator segment extended from an opposite end of said transverse radiator segment and curved forward and backward along a longitudinal direction; said grating conductor comprises a transverse connection segment, a longitudinal connection segment extended from said transverse radiator segment to said transverse connection segment, and a plurality of transverse extension segments respectively extended from said longitudinal connection segment in direction toward said longitudinal radiator segment and spaced from one another in a parallel manner within the area between said transverse radiator segment and said transverse connection segment.

3 . The coupling-type grating antenna as claimed in claim 2 , wherein said monopole antenna element further comprises a short-circuit conductor extended from said transverse radiator segment of said radiator to the said transverse extension segment that is disposed adjacent to said transverse radiator segment.

4 . The coupling-type grating antenna as claimed in claim 2 , wherein said coupling grating body comprises a plurality of notches.

5 . The coupling-type grating antenna as claimed in claim 4 , wherein a projection position of said notches of said coupling grating body is at least overlapped with said transverse connection segment of said grating conductor and a part of said longitudinal radiator segment of said radiator.
