摘要： A circular polarized wave reception antenna has a monopole antenna having a pole portion and an ground plate for grounding one terminal of the pole portion and a polarization converting arrangement disposed around the monopole antenna. The polarization converting arrangement has a plurality of helical leads extending in a helical fashion along the pole portion with apart from the pole portion by a predetermined distance. Each of the helical leads has an end grounded in said ground plate. The helical leads are disposed at equal angular spaces around the pole portion. When a resonance wavelength λ is equal to 128.3 mm, the predetermined space is equal to 20 mm. Each helical lead has a length of λ/4. A pitch angle included between the ground plate and each helical lead is equal to 40 degrees.

摘要： To provide a thin wideband antenna unit capable of shrinking the size of a radiation element in a case where a dielectric is not used.In a wideband antenna unit 10 having a ground plate 12 and a flat shaped radiation element 14 disposed on a plane (x, y) flush with a plane where the ground plate extends, the radiation element 14 has an elliptically shape. The radiation element 14 and the ground plate 12 are apart from each other by a predetermined feeding distance ΔFD. A ratio between an outside diameter 2aout in an ellipse's x-direction and an outside diameter 2bout in an ellipse's y-direction is 8:5. The elliptically shaped radiation element 14 has an elliptically shaped opening 14a which is concentric O with the elliptically shape. An inside diameter 2bin in the ellipse's y-direction is half of an outside diameter 2bout in the ellipse's y-direction. It is desirable that an inside diameter 2ain of the elliptically shaped opening 14a in the ellipse's x-direction is not more than half of the outside diameter 2aout in the ellipse's x-direction.
