    • The invention provides a dual-access antenna fabricated on a substrate. In one embodiment, the antenna includes a first monopole element, at least one grounded parasitic element located proximate the first monopole element, wherein the separation between the monopole and the grounded parasitic element exhibits a conductive profile which varies the waveguide characteristics of the antenna assembly. The conductive profile is provided by a stepped or angled profile on the or each grounded parasitic element which faces and extends away from first monopole element. This antenna covers the frequency range 900 to 2300 MHz. The antenna includes a secondary grounded element located at an outer position relative to the or an associated grounded parasitic element. In a preferred embodiment, the antenna includes two grounded parasitic elements located on opposite sides of the first monopole element. To provide dual-access communication, the antenna includes a second monopole element positioned so that there is little or no coupling or interference. This secondary monopole is adapted for communications in the 2.4–2.5 GHz band. The invention is particularly suitable for small devices communicating at a broad range of frequencies where a small form-factor wideband antenna is required.
    • 本发明提供一种制造在基板上的双重接入天线。 在一个实施例中,天线包括第一单极元件,位于第一单极元件附近的至少一个接地寄生元件,其中单极子和接地寄生元件之间的间隔表现出改变天线组件的波导特性的导电轮廓。 导电轮廓由位于或每个接地的寄生元件上的阶梯形或倾斜轮廓提供,其面向并远离第一单极元件延伸。 该天线覆盖900至2300 MHz的频率范围。 天线包括位于相对于或相关联的接地寄生元件的外部位置处的次级接地元件。 在优选实施例中,天线包括位于第一单极元件的相对侧上的两个接地的寄生元件。 为了提供双重访问通信,天线包括定位成使得很少或没有耦合或干扰的第二单极元件。 该次级单极子适用于2.4-2.5 GHz频段的通信。 本发明特别适用于需要小尺寸宽带天线的广泛频率通信的小型设备。

    • The invention provides for a planar antenna assembly supported on a substrate. The antenna includes a monopole element, at least one grounded parasitic element located proximate the monopole element, wherein each grounded parasitic element is grounded to a planar ground plane and incorporates a conductive profile shaped so that the separation between the parasitic element and the monopole adjacent it, varies along the length of the parasitic element. In one embodiment, the separation between the monopole and the parasitic element is provided by a stepped or angled edge on the or each grounded parasitic element, and the profile faces and extends away from monopole element. The antenna may include two grounded parasitic elements located on opposite sides of the monopole element and the, or each, grounded parasitic element may include a foot extending towards a base part of the monopole element which is adjacent the ground plane. The particular shape of the parasitic elements provides for good wideband performance and the antenna may find particular application in small or handheld devices where small form-factor antennas are required.
    • 本发明提供了一种支撑在基板上的平面天线组件。 天线包括单极元件,位于单极元件附近的至少一个接地的寄生元件,其中每个接地的寄生元件接地到平面接地平面并且包括形状为导电的轮廓,使得寄生元件和与其相邻的单极子之间的间隔 ,沿寄生元件的长度变化。 在一个实施例中,单极子和寄生元件之间的间隔由在或接地的寄生元件上的阶梯形或成角度的边缘提供,并且轮廓面并且远离单极元件延伸。 天线可以包括位于单极元件的相对侧上的两个接地的寄生元件,并且每个接地的寄生元件可以包括朝与接地平面相邻的单极元件的基部延伸的脚。 寄生元件的特定形状提供良好的宽带性能,并且天线可以在需要小形状因子天线的小型或手持式设备中找到特定应用。
