To avoid differences in received power on the multiple input power ports causing a power supply to supply higher power than designed or regulated, the input power ports in the remote unit are electrically isolated from each other. Further, the received power on the multiple power inputs ports can be controlled to be proportionally provided to the combined output power according to the maximum power supplying capabilities of the respective power supplies.

  • Patent number: 9755723
    Abstract: A method, system, and medium are provided for improving uplink performance of an antenna array configured for downlink beam forming. Beam forming requires an antenna element spacing that results in correlated downlink signals. Uplink reception preferably uses an element spacing such that uplink signals are uncorrelated. For an eight-element antenna configured for beam forming, using eight-branch combining to produce a single resultant signal is thus less than optimal. In an embodiment, non-adjacent elements in the antenna array, which receive uncorrelated signals, may be combined in pairs with two-branch combining. The four resultant signals may then be combined using four-branch combining to provide a single resultant signal.

  • Patent number: 9583836
    Abstract: An antenna is connected to a first end of a high-frequency transmission line, and a connector is connected to a second end of the high-frequency transmission line. A characteristic impedance of a microstrip line is higher than characteristic impedances of first and second strip lines, and a characteristic impedance of a coplanar line is higher than a characteristic impedance of the second strip line. Thus, at a certain frequency, a standing wave develops in which the position of the microstrip line and the position of the coplanar line are maximum voltage points and three-quarter-wavelength resonance is a fundamental wave mode. Thus, the cutoff frequency of the high-frequency transmission line is high, and an insertion loss of a signal is significantly reduced to be low over a wide band.

  • Patent number: 9496600
    Abstract: Metal housing walls may form an antenna cavity. Antenna structures may be formed from metal traces mounted on a carrier in the antenna cavity. The antenna structures may form an array of antennas such as an array of planar inverted-F antennas. The housing may have an inner cavity wall such as a circular inner cavity wall. The planar inverted-F antennas may lie between the inner cavity wall and the metal walls of the housing. Each planar inverted-F antenna may have an associated parasitic antenna resonating element. The planar inverted-F antennas may be configured to resonate in upper and lower frequency bands. The parasitic elements may each extend inwardly from the metal walls and may broaden the frequency response of the planar inverted-F antennas in the lower frequency band. Parasitic elements may be used to isolate antennas from each other.

  • Patent number: 9356683
    Abstract: An apparatus and a method for scheduling and a power control of a relay system that is capable of stable operation an environment where sufficient isolation between antennas is not ensured. The apparatus includes a scheduler for allocating resources to a zone not experiencing inter-antenna interference in an initial resource allocation, classifying users based on vulnerability to the interference, and allocating resources to a zone experiencing the interference, and a power controller for setting the resources of the zone experiencing the interference to a lower power than the resources of the zone not experiencing the interference to minimize the inter-antenna interference.

  • Patent number: 9231300
    Abstract: The present invention is a grounded mast clamp current probe apparatus. The apparatus can have a current probe substantially enclosed by at least one housing. The housing forms an electrostatic shield that prevents passage of electricity to or from the current probe. A plurality of grounding elements are connected to the outer surface of the housing and radiate outwardly from the outer circumference of the housing. Each of the grounding elements radiates at a frequency angle ?, the angle formed between a longitudinal axis of the housing and a longitudinal axis of the grounding elements. The bandwidth and resonant frequency of the current probe is dependent on the frequency angle ?.

  • Patent number: 9112276
    Abstract: An antenna assembly with wide bandwidth and low Passive Intermodulation (PIM) characteristics is described for use in Distributed Antenna Systems (DAS) and other applications which require low PIM levels. The antenna can be configured to cover multiple cellular frequency bands to provide a single antenna solution for use with multiple transceivers. A single conductor radiator design along with features integrated into the ground plane result in low PIM characteristics during high power transmission. One or multiple parasitic elements can be coupled to the driven antenna to enhance bandwidth while still maintaining low PIM characteristics.
