摘要： A quadrifilar antenna having helical windings is fed by a phase shift feed network, each winding having an open circuit termination element, the phase shift feeding network having forward directional phase shift paths from a feed input to phase shift feed output ports, and having a first reverse directional transmission path from one or more of the phase shift feed output ports back to a first isolation port, and a second reverse directional transmission path from another one or more of the phase shift feed output ports back to a second isolation port, the first and second isolation ports isolated from the forward directional phase shift paths, and a differential termination impedance, floating from ground, connected the first and second isolation ports. Optionally, the differential termination impedance is frequency selective.

摘要： A mobile satellite radio equipped with a phased array antenna configures the phased array antenna in one or more non-directional operating modes in order to initially detect a signal from a communication satellite. Once a signal has been received from the satellite, frequency information determined in the course of operating in the one or more non-directional modes is used to configure the mobile satellite radio for operation in a subsequent stage when the phased array antenna is configured in a directional mode. In the subsequent stage the phased array antenna is used to scan a solid angle space to determine the direction of the satellite. Thereafter the antenna is used in the directional mode for satellite communication.

摘要： A multi-mode, multi-band antenna system for a handheld wireless device includes a Quadrafilar Helix Antenna (QHA) that radiates circularly polarized waves is fed by a co-axial cable. The co-axial cable is also used in combination with the QHA as a monopole antenna. Because of the distinct electromagnetic field patterns of the QHA versus the combination of the QHA and the co-axial cable operating as a monopole antenna, the cross coupling between the two modes is low. In certain embodiments the co-axial cable can itself be formed into a helix in order to reduce the physical length of the antenna system while maintaining an electrical length desired to supported certain frequency bands in the monopole mode. According to certain embodiments a post which also serves to increase the effective electric length of the co-axial cable and thereby support a lower frequency band is provided along the centerline of the QHA.
摘要翻译：用于手持无线设备的多模式多频带天线系统包括辐射圆偏振波的Quadrafilar螺旋天线（QHA）由同轴电缆馈送。同轴电缆也与QHA组合用作单极天线。由于QHA的不同电磁场图案与QHA和作为单极天线的同轴电缆的组合相互作用，两种模式之间的交叉耦合较低。在某些实施例中，同轴电缆本身可以形成为螺旋，以便在保持在单极模式中支持的某些频带所需的电长度的同时减小天线系统的物理长度。根据某些实施例，沿着QHA的中心线提供也用于增加同轴电缆的有效电长度并由此支撑较低频带的柱。

摘要： An antenna system includes a metal housing including a first edge and a second edge that meet at a corner and a slot located proximate the second edge that extends from the first edge parallel to the second edge defining a strip and an antenna located behind and in close proximity to the strip. The antenna is coupled to the strip. A parasitic element is located proximate the antenna and the strip includes a ground coupling that crosses the slot in spaced relation thereto. The parasitic element assists in establishing second and third higher frequency modes of the antenna system.
