Title: ANTENNA
Abstract:
Provided in the embodiments of the present invention is an antenna, comprising: a radiator and a feed which are electrically connected, the radiator being positioned above the feed; the radiator comprises a first substrate, as well as a first copper-clad layer and a second copper-clad layer which are arranged on an upper surface and a lower surface of the first substrate respectively; the feed comprises a second substrate, as well as a third copper-clad layer and a fourth copper-clad layer which are arranged on an upper surface and a lower surface of the second substrate respectively; at least one first feed gap is arranged on the second copper-clad layer, and a second feed gap corresponding to the first feed gap is arranged on the third copper-clad layer; the second feed gap feeds to the radiator by means of the corresponding first feed gap; each second feed gap corresponds to two groups of metal through holes penetrating the first substrate from top to bottom, and the two groups of metal through holes are respectively positioned on two sides of the second feed gap; and a symmetrical projection of one group of metal through holes in the two groups of metal through holes on an opposite side has an overlap area with the other group of metal through holes, wherein each second feed gap is used as the axis of symmetry. Therefore, side lobes of the antenna may be avoided or reduced.
