    • A dielectric substrate 101 is a square substrate having a dielectric constant εr, thickness t and length per side of Wd. A grounding conductor 102 is provided on one side of the dielectric substrate 101 in the same shape as the dielectric substrate 101. An MSA element 103 is formed of square copper foil having a length per side of Wp in the center of the other side of the dielectric substrate 101. Mono-pole antennas 104a to 104d are copper wires having a diameter D and length L and are spaced uniformly on diagonals of the MSA element 103 and disposed perpendicular to the dielectric substrate 101. The MSA element 103 or mono-pole antennas 104a to 104d is selectively fed, whichever has higher reception power. When the mono-pole antennas 104a to 104d are selected, the phases and amplitudes of the respective elements are controlled. This makes it possible to obtain a high gain in all directions over a hemisphere face from the horizontal direction to the vertical direction and provide an antenna apparatus in a small and simple configuration.
    • 电介质基板101是具有介电常数ε,厚度t和Wd侧的长度的方形基板。 接地导体102以与电介质基板101相同的形状设置在电介质基板101的一侧.MSA元件103由方形铜箔形成,该方形铜箔的边的另一侧的中心具有Wp侧的长度 电介质基板101.单极天线104a至104d是具有直径D和长度L的铜线,并且均匀分布在MSA元件103的对角线上并垂直于电介质基板101设置.MSA元件103或单电极基板101。 选择性地馈送极天线104a至104d,以较高的接收功率为准。 当选择单极天线104a至104d时,控制各个元件的相位和振幅。 这使得可以从水平方向到垂直方向在半球面上获得在所有方向上的高增益,并且以简单的结构提供天线装置。

    • Linear elements 101a to 101d are conductors, which have the element length equivalent to half a wavelength, have been placed so that they may draw a diamond shape. Delay elements 102a and 102b are bent conductors, which have a total length equivalent to one fourth wavelength and a length L2 equivalent to one eighth. The linear elements 101a and 101c are connected one another via the delay element 102a, while the linear elements 101b and 101d are connected one another via the delay element 102b. A feeding section 103 is connected to each of the ends of the linear elements 101a and 101b for feeding power to them. Between the tips of the linear elements 101c and 101d, a gap with a length L3 is left. A reflector 104 has been placed at a distance h from a diamond-shape antenna with delay elements along the −Z axis, the distance h being equivalent to 0.42 wavelength. This achieves the antenna device, which may be suitably mounted on any of small wireless apparatuses and form a primary beam, of which horizontally-polarized wave or vertically-polarized wave tilts toward the horizontal direction.
