    摘要： An apparatus, e.g. a hybrid antenna, includes a plurality of antenna arrays. Each array includes antenna elements, and each array is located on a polygonal antenna body such that each array faces a different direction. An RF network includes first and second duplexers and a divider. The first duplexer is configured to split a received multifrequency drive signal into a first component having a first frequency and a second component having a second frequency. The divider is configured to split the first component into attenuated portions, and to direct one of the attenuated portions to a first of the plurality of antenna arrays. The second duplexer is configured to combine another of the attenuated portions with the second drive signal component to form a combined drive signal component, and to direct the combined drive signal component to a second of the antenna arrays.

    摘要： Multi-conductor cables for telecommunication systems are disclosed. One multi-conductor cable may include a plurality of fiber-optic conductors and/or power conductors extending within an outer jacket in a main body portion of the cable, and extending outside of the outer jacket in a break-out portion of the cable. A break-out boot may be attached to the outer jacket and may surround the conductors in a break-out portion of the cable. Potting material may be provided in the break-out boot within spaces between adjacent conductors to provide innovative sealing of the break-out portion.

    摘要： An angle diversity antenna system utilizes a first antenna, a second antenna, and a panel combiner coupled to the first and second antenna. In a transmit mode, the first and second antenna are coupled to a transmit sum channel of the panel combiner. In a receive mode, either the sum channel or a difference channel of the panel combiner is chosen as the active channel. By monitoring the sum channel and difference channel, the antenna system according to the present invention is able to select the channel which supplies the greatest signal strength.

    摘要： An improved transmission line for RF communications. A transmission line comprising a center conductor; a dielectric layer surrounding the center conductor; a bimetallic outer conductor including an outer conductive layer and an inner conductive layer; wherein the outer conductive layer and the inner conductive layer are of differing materials; and the inner conductive layer is copper or copper alloy; and an insulating jacket surrounding the bimetallic outer conductor. Other aspects do not require the center conductor or the dielectric layer. Further aspects include a bimetallic center conductor. Advantages of the transmission line include imperviousness to signal loss due to surface abnormalities (due to inner conductive layer being interior to and encapsulated by outer conductive layer); the potential for significant cost savings in material; excellent RF communications signal propagation; and a significant reduction in weight.

    摘要： 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.

    摘要： A novel junction design was developed for use with in-line combiner networks to minimize electrical length between the resonators being combined and to optimize coupling. It consists of a combiner comprising a plurality of cavity resonators coupled to a combining mechanism. The combining mechanism is placed outside of each resonator a prescribed distance above the ground plane. Combiner pairs are created by connecting two cavities to each other using quarter-wave lines. The central combiner pair is directly connected to the output connector through a common port. The quarter-wave junctions not directly connected to the output connector are then connected to the output port through half-wavelength lines. Iris or aperture coupling is controlled by a sliding cover that is adjusted using a free-rotating screw and is secured with locking screws to ensure good electrical and RF grounding.
