    • The invention relates to a broadband antenna means which comprises a first and a second helical antenna (203, 207) wherein the antennas (203, 207) have different resonance frequencies. An antenna which has essentially a larger bandwidth than the bandwidth of an individual helical antenna is formed in coaction between the helical antennas (203, 207), by arranging the antennas coaxially and in generally the same axial positions, wherein the helical antennas (203, 207) are separated galvanically, possibly with the exception of at respective supply points. When fitted to portable equipment, the helical antennas (203, 207) can be combined with an axially movable straight wire antenna.
    • 本发明涉及一种宽带天线装置,其包括第一和第二螺旋天线(203,207),其中天线(203,207)具有不同的谐振频率。 通过将天线同轴布置在大致相同的轴向位置,在螺旋天线(203,207)之间的共同作用下,形成具有比单个螺旋天线的带宽基本上更大的带宽的天线,其中螺旋天线(203, 207)电流分离,可能除了在各供应点之外。 当安装到便携式设备上时,螺旋天线(203,207)可以与轴向可移动的直线天线组合。

    • The deployable helical antenna of the present invention and helical antenna deployment system includes a helical antenna having a plurality of helical filars and at least two guide plates positioned with respect to the helical filars. Each of the guide plates is provided with a plurality of guide elements operably attached to a corresponding helical filar. The novel helical antenna of the present invention can be collapsed into a stowed position such that each of the helical filars, and portions thereof, are tightly and efficiently layered one over another. Upon actuation of a retention mechanism, the stored energy in each of the collapsed helical filars initiates antenna deployment whereby the guide elements accurately and reliably control the movement and final position of a corresponding helical filar. The novel deployment system of the present invention controls the operational parameters of the antenna (such as diameter, height, and pitch angle), insures quick and reliable antenna deployment, and increases the lateral stiffness of the deployed antenna.
    • 本发明的可展开螺旋天线和螺旋天线展开系统包括具有多个螺旋丝状物的螺旋天线和相对于螺旋丝状物定位的至少两个引导板。 每个引导板设置有可操作地连接到相应的螺旋丝状体上的多个引导元件。 本发明的新型螺旋天线可以折叠成收起位置,使得每个螺旋丝及其部分彼此紧密有效地分层。 在启动保持机构时,每个收缩的螺旋丝状体中存储的能量启动天线展开,由此引导元件精确可靠地控制相应螺旋丝状丝的运动和最终位置。 本发明的新型部署系统控制天线的操作参数(如直径,高度和俯仰角),确保快速可靠的天线部署,并增加部署天线的横向刚度。
