titleOfInvention | Aperture-coupled antenna |
abstract | The present invention provides an aperture-coupled antenna (100) having a first radiation electrode (130), an earth surface (110) and a waveguide (140), which is designed to supply power to the antenna. The waveguide (140) is arranged, spaced apart from the earth surface (110), on a first side of the earth surface (110), and the first radiation electrode (130) is arranged, spaced apart from the earth surface (110), on a second side of the earth surface (110). The earth surface (110) has an aperture (120), which comprises a first slot (150) in the earth surface (110), a second slot (152) in the earth surface (110) and a third slot (154) in the earth surface (110). The first slot (150) and the second slot (152) together form a slot in the form of a cross. The third slot (154) runs through a point of intersection between the first slot (150) and the second slot (152). The waveguide (140) and the radiation electrode (130) are also arranged such that power from the waveguide (140) can be coupled to the patch via the aperture (120). An antenna structure according to the invention has a high degree of polarization purity and a large impedance bandwidth. In addition, an antenna structure according to the invention makes it possible to produce a planar dualband or multiband antenna with circular polarization. |
