摘要： A dual polarized high gain and wideband complementary antenna is presented herein. A dual polarized antenna can include a ground plane, a folded dipole portion electrically coupled to the ground plane, a shorted patch antenna portion including an open end that is electrically coupled to the folded dipole portion, and a metal plate located at a bottom portion of the dual polarized antenna. In one example, the folded dipole portion can include four folded dipoles. Further, the open end of the shorted patch antenna portion can be electrically coupled to the folded dipole portion using the metal plate. Further, the dual polarized antenna can include two ports—each port including a pair of feeding sources, and each feeding source configured to generate an electric dipole and a magnetic dipole. In another example, magnitudes of the electric dipoles can be equivalent, and magnitudes of the magnetic dipoles can be equivalent.

摘要： The present invention provides an open-aperture waveguide fed slot antenna including a feeding section on a substrate integrated waveguide, an H-shaped slot, a matched end, and a bottom metal layer. One end of the feeding section is open and connected to the slot, providing energy feeding to the slot. A long side of the center section of the slot is connected to a top metal part of the feeding section. Another side is connected to the matching end. The matching end includes metal which is connected to the slot, the metallic via wall and the bottom metal of the feeding section which is connected to the metallic via wall. The antenna has high gain, wide gain bandwidth, a simple structure, and low processing cost and can be applied to millimeter-wave frequency bands as well as other frequency bands.

摘要： The present disclosure relates to a waveguide fed open slot antenna. In some examples, the antenna comprises a waveguide section, a slot, a matching load, a waveguide bottom extension, and a vertical metal wall. The waveguide section can be in the form of a rectangular waveguide or a substrate integrated waveguide (SIW). The slot can comprise a rectangle, with one of its long sides abutting the top surface of the waveguide section, and another long side abutting the matching load, while the two short sides do not connect any metal. The waveguide bottom extension can be rectangular. The end of the waveguide bottom extension and the edge of the matching load on the side close to the open slot can be connected together by the vertical metal wall. In this way, the slot can be excited.
