    摘要: Reflector antennae and related structures and methods are described. The reflector antennae may have a deep f/D ratio and use an offset corrugated horn. Pivoting feed arms may be included for connecting a feed horn to a dish of the antenna. Radomes are also described, which may be formed of two or more pieces.

    摘要: Antennae are described. The antennae may be GPS antennae configured to receive GPS signals at both the L1 and L2 frequencies. The antennae may include patches and polarizers which allow the antennae to receive right-hand circularly polarized GPS signals from GPS satellites. In some situations, the polarizers may include a meta-material. The meta-material may in some situations include circuit components formed on a suitable substrate.

    摘要: A balun component or structural subassembly, for use in conjunction with an antenna radome assembly, comprises a two-sided printed circuit board substrate having a longitudinal axis, wherein each side of the two-sided printed circuit board substrate is asymmetric with respect to itself but is in effect anti-symmetric with respect to the opposite side of the two-sided printed circuit board substrate in a 180° out-of-phase manner such that the entire two-sided printed circuit board balun component or structural subassembly exhibits diametrical symmetry with respect to the longitudinal axis of the overall two-sided printed circuit board substrate. Such diametrical symmetry with respect to the longitudinal axis of the overall two-sided printed circuit board substrate enables operatively associated antenna sensor amplitude and phase comparison assemblies or systems to achieve well-behaved and unsquinted amplitude and phase patterns regardless or independent of polarization in order to reduce angle of arrival (AOA) errors. In addition, the balun component or structural subassembly comprises tapered transformer structure which effectively converts the coaxial feed point impedance values of incoming signals to signals having impedance values at the output or downstream end which are able to achieve good impedance matching with the aforenoted spiral circuit component or assembly of the radome elements or components of the overall antenna structure. Still further, such tapered transformer structure positively affects or enhances the range of bandwidth frequencies over which the balun component or structural subassembly is capable of operating.

    摘要: An compact and rugged antenna system particularly suited to direction finding includes a plurality of antenna arrays for receiving respective frequency bands and colocated on a mast with separation between antenna arrays along the mast. The mast includes a coil wound of an insulator and functioning as a loaded inductor to shift the mast resonance out of the frequency band of the antenna system. A VHF dipole array having elements shaped to reduce scattering to UHF and SHF arrays is supported on movable arms which allow retraction that reduces height and provides mechanical protection to one or more other arrays as well as damping against vibration by contacting the mast with shaped portions of the dipole elements. The bowtie elements of the UHF array are angled at a central region to optimize array diameter at low UHF frequencies. A finned RF electronics housing is preferably provided which reduces solar loading and dissipates heat from antenna electronics. Asymmetrically keyed fittings are provided to permit accurate antenna system, array and element positioning and replaceable components and wiring, both internally and externally of the housing, is held in position to allow field repairs without recalibration.
