摘要： A family of FE dielectric-tuned antennas and a method for frequency tuning a wireless communications antenna are provided. The method comprises: forming a radiator; forming a dielectric with ferroelectric material proximate to the radiator; applying a voltage to the ferroelectric material; in response to applying the voltage, generating a dielectric constant; and, in response to the dielectric constant, communicating electromagnetic fields at a resonant frequency. Some aspects of the method further comprise: varying the applied voltage; and, modifying the resonant frequency in response to changes in the applied voltage. Modifying the resonant frequency includes forming an antenna with a variable operating frequency responsive to the applied voltage. Alternately stated, forming an antenna with a variable operating frequency includes forming an antenna with a predetermined fixed characteristic impedance, independent of the resonant frequency.

摘要： An antenna system comprising a plurality of dipole elements formed from a single piece of material. The plurality of dipole elements is attached to a reflector plate with a single supporting base and forms horizontally or vertically stacked radiation elements. Tabs located between the center of the single piece and legs of the dipole elements and are bent at an angle to form a symmetrical axis in the center of slots separating the plurality of dipole elements to attenuate the radiation caused by current flowing around the slots. The plurality of dipole elements are selected to achieve different radiation patterns and can be formed into different shapes to achieve different lobe shapes.

摘要： A dipole antenna for selecting an antenna polarization plane of the strongest polarization energy includes at least two dipole antenna elements (1, 2) arranged perpendicularly to each other to form a single antenna, a PCB (3), and two feeding lines (4). Each dipole antenna element includes two T-shaped dipole arms (11, 12). This structure makes use of two planes of the XZ-plane, XY-plane and YZ-plane, and also makes the dipole antenna more compact. The antenna obtains optimum polarization energy by selecting the strongest energy plane. This achieves maximized radiation efficiency under any particular orientation of the dipole antenna. The strongest energy plane is selected by controlled switching, by means of dual-fed signal mode. The dipole arms of each dipole antenna element are disposed on opposite surfaces (31, 32) of the PCB, to minimize interference.

摘要： An planar ultra wide bandwidth (UWB) antenna that provides integration of electronics is disclosed. The antenna has a first balance element that is connected to a terminal at one end. A second balance element is connected to another terminal at one end. The second balance element has a shape that mirrors the shape of the first balance element such that there is a symmetry plane where any point on the symmetry plane is equidistant to all mirror points on the first and second balance elements. Each of the balance elements is made of a generally conductive material. A triangular shaped ground element is situated between the first balance element and the second balance element with an axis of symmetry on the symmetry plane, and oriented such that the base of the triangle is towards the terminals. Accordingly, the ground element and each of the balance elements form two tapered gaps which widen and converge at the apex of the ground element as the taper extends outwardly from the terminals. Under this arrangement, sensitive UWB electronics can be housed within the perimeter of the ground element, thereby eliminating transmission line losses and dispersion, and minimizing and system ringing. A resistive loop connected between the first and second balance elements extends the low frequency response and improves the VSWR. A connection of an array of elements is disclosed that provides a low-frequency cutoff defined by the array size rather than the element size.
摘要翻译：公开了一种提供电子集成的平面超宽带（UWB）天线。天线具有在一端连接到终端的第一平衡元件。第二平衡元件在一端连接到另一终端。第二平衡元件具有反映第一平衡元件的形状的形状，使得存在对称平面，其中对称平面上的任何点与第一和第二平衡元件上的所有镜像点等距。每个平衡元件由通常导电的材料制成。三角形接地元件位于第一平衡元件和第二平衡元件之间，在对称平面上具有对称轴线，并且被定向成使得三角形的基座朝向端子。因此，当锥体从端子向外延伸时，接地元件和每个平衡元件形成两个锥形间隙，该间隙在接地元件的顶点处变宽并会聚。在这种布置下，敏感的UWB电子器件可以容纳在接地元件的周边内，从而消除了传输线损耗和色散，并最小化了系统振铃。连接在第一和第二平衡元件之间的电阻回路延伸了低频响应并改善了VSWR。公开了一种元件阵列的连接，其提供由阵列尺寸而不是元件尺寸限定的低频截止。

摘要： A radiating element for use in a dual-polarized radiating apparatus with isolation between polarization channels has a dielectric body having one or more conductive radiators thereon. The dielectric body has oppositely outwardly extending lateral edge portions which extend beyond lateral outer edges of the conductive radiators. Cooperating joining structure interengages an edge of each dielectric body with an adjacent edge of an adjacent dielectric body to form at least a portion of the dual polarized radiating apparatus.

摘要： A meander line loaded antenna provides a wide instantaneous bandwidth with a first planar conductor extending orthogonally from a ground plane, a second planar conductor substantially parallel to the ground plane and separated from the first planar conductor by a gap, a meander line interconnecting the first and second planar conductors across the gap, and a third conductor connecting the second planar conductor to ground.

Each of the individual antennas, the opposed pairs of individual antennas, and the quadrature antennas may be stacked with each lower antenna forming the ground plane for the antenna mounted thereon.
