  • Patent number: 8175648
    Abstract: A super economical broadcast system and method are provided. The system includes a plurality of base transceiver stations that define a plurality of respective cells, each base transceiver station includes a phased-array antenna having a plurality of sectors, each sector has a plurality of vertically-arranged antenna panels, and each antenna panel has a plurality of vertically-arranged radiators disposed in at least two staggered columns. The method includes forming a horizontally and vertically shaped beam using a plurality of vertically-arranged antenna panels, in which each antenna panel has a plurality of vertically-arranged radiators disposed in at least two staggered columns, and transmitting a power distribution that has an essentially uniform field strength over a near zone, a middle zone and at least a portion of a far zone.

  • Patent number: 8115696
    Abstract: A phased-array antenna panel for a super economical broadcast system is provided. The phased-array antenna panel system includes an antenna panel support member, a first pair of striplines and a second pair of striplines. The antenna panel support member includes a front reflector surface to support first and second columns of constantly-spaced, crossed-dipole radiators, a first pair of signal ground cavities disposed beneath the first column of crossed-dipole radiators, a second pair of signal ground cavities disposed beneath the second column of crossed-dipole radiators, and a rear surface including first and second pairs of signal distribution cable connectors. The first pair of striplines are respectively disposed within the first pair of signal ground cavities and are coupled to the first pair of signal distribution connectors and the first column of crossed-dipole radiators.
