  • Forty-five degree dual broad band base station antenna
    Patent number: 9293809
    Abstract: The present invention relates to a multiband antenna specifically adapted for use with a Base Station Antenna (“BSA”). The present invention provides narrow azimuth or horizontal beamwidth (“HBW”) having 45 degrees and operational over four frequency bands. The composite antenna topology and associated circuitry described in embodiments achieves reduced antenna installation requirements and allows for ease of network deployment or reconfiguration at reduced cost. Embodiments employ an array of low band radiating elements and two sets of high band radiating elements. The first set is co-located within an array of low band radiating elements. The second set of is offset and outside the low band radiating elements. An RF feed network energizes the first and second set of high band radiating elements to compensate for interference between the high and low band elements.
