  • Patent number: 10148002
    Abstract: The embodiments herein use polarization diversity between antennas where the antennas for one cell are, e.g., horizontally polarized and antennas for the other cell are vertically polarized. In one embodiment, the antennas for a macro cell are vertically polarized while micro cell antennas are horizontally polarized. In one example, the micro cell antennas are printed antennas that form a loop that is co-planar with the magnetic fields generated by the macro cell antennas when transmitting. Because the magnetic fields are co-planar (rather than orthogonal) to the current flowing through the loop in the micro cell antenna, the effect of the electromagnetic signals emitted by the macro cell antenna is reduced. This may permit dual radio network devices to have improved performance when operating simultaneously—e.g., when the macro cell radio is transmitting and the micro cell radio is receiving at or near the same frequency band.

  • Patent number: 9276328
    Abstract: A small-caliber, high-performance broadband radiator allows two unit arms of the first and second group of dipoles to be folded inwards, an included angle of 40°-50° is formed between two unit arms of the first/second groups of dipoles and the first/second unit racks, and the unit arms of the first and second groups of dipoles are arranged linearly at interval while flexural loading sections are provided and also connected by dielectric medium. Hence, the broadband radiator allows significant reduction of the aperture of the broadband radiator, and there is a larger adjustment space for the gap of the radiator array, so the interference of low and high bands is less. This allows for improved performance, thus reducing the configuration size and manufacturing cost of antennas, and creating better industrial benefits with improved applicability.

In another embodiment, the dipoles are printed on a PCB.

  • Patent number: 7460083
    Abstract: The antenna assembly is circularly polarized and may be able to receive multiple independent signals. The antenna assembly includes a plurality of electrically conductive layers arranged about an axis to define a series of adjacent corner reflectors (e.g. four to eight corner reflectors), and a plurality of spiral antenna elements. Each spiral antenna element extends across a respective open end of a corresponding corner reflector. Each corner reflector may have an equal corner angle, and each spiral antenna element may be a bifilar spiral antenna element and/or a log spiral antenna element. A housing may contain the corner reflectors and the spiral antenna elements. Electronic circuitry may be coupled to the plurality of spiral antenna elements and contained within the housing. The antenna is preferential for television reception on multiple channels and directions without consumer adjustment, as the antenna provides spatial, angular and frequency diversity through simultaneous overlapping beams.

  • Patent number: 7417597
    Abstract: Ground based GPS antennas for differential applications may be subject to intentional or other interference signals incident at low elevation angles. Described GPS antenna systems are usable to provide an antenna pattern having a vertically-steerable null. An array of vertically spaced radiator units having omnidirectional azimuth characteristics provides a primary reception pattern. Vertically intermixed radiator units employed on a separate or shared basis provide an auxiliary reception pattern. By subtractively combining the auxiliary pattern with the primary pattern and adjusting the relative signal level of the auxiliary pattern a vertically-steerable pattern null is provided. The antenna system may include an adaptive control system responsive to an antenna output signal to derive a steering signal to adjust the relative signal level of the auxiliary pattern to steer the vertically-steerable null to provide interference suppression. Antenna systems and methods are described.

  • Publication number: 20080111757
    Abstract: The invention relates in part to a folded dipole having a dipole axis and a pair of arms which together have a profile which is concave on one side and convex on the other when viewed along the dipole axis. The dipoles may be arranged as a dipole box around a central region, typically in a generally circular or square configuration. Further elements may be placed in the dipole box or in the gaps between dipole boxes. The antenna may be a single-band antenna, or a multi-band antenna with the further elements operating in a different frequency band to the dipole boxes. The further elements may be concentric dipole boxes. The invention is particularly suited for use in a cellular base station panel antenna. A novel coaxial to microstrip transition is also described.

  • Patent number: 6744412
    Abstract: To provide horizon to zenith reception coverage for Differential GPS operations, two antennas with complementary patterns may be used. An antenna for high-angle coverage includes a ring of four dipoles excited to provide progressive-phase-omnidirectional (PPO) coverage. A cylindrical (e.g., octagonal) structure, with an upper edge at the diode horizontal centerline, extends upward from a ground plane section. An absorber configuration having a serrated upper edge portion extends around the dipoles above the cylindrical structure and has radiation absorption properties. For an octagonal configuration, the absorber configuration may include eight resistance card sections with triangular portions extending above the wall structure. A conical antenna pattern expanding upwardly can provide omnidirectional coverage above a selected elevation angle (e.g., above 55° elevation).

  • Patent number: 6728554
    Abstract: A wireless communication network which includes an antenna array for receiving and transmitting signals to and from remote users which is capable of adapting to widely varying traffic levels. Different antenna elements can be turned on during high user periods and off when there are fewer users. Also, beam width can be varied, with fewer antennas having wide beams in use when traffic levels are low and more antennas with narrow beams when traffic is high. Generally, the maximum capability uses 180 antenna elements with beam widths of about 2° to cover a full 360°. This network can act as either a circuit switched network or a packet switched network, as desired.

  • Publication number: 20030222830
    Abstract: A polarized antenna for sending and receiving polarized radio frequency signals is disclosed which includes a dipole and a reflector plate. The dipole is formed as a single part including the radiating arms and feeding structures, thereby requiring minimum assembly. This dipole can be formed by molding conventional materials, such as copper, aluminum, and plastic, which can then be plated. The feeding structure through which the cable passes features a slotted aperture. The impedance of the dipole is based on the width of these apertures and the size of the cable conductor. By having a single-body construction, the dipole of the present invention provides, good impedance, low intermodulation distortion, good port-to-port isolation, and good pattern purity.
