Abstract: A cellular base station antenna is provided with a plurality of radiating elements arranged among a plurality of columns disposed over a reflector. In accordance with one embodiment, the first array of antenna elements and second array of antenna elements are arranged across three vertically arranged columns. At least a first array of antenna elements includes at least some of said plurality of radiating elements on each one of the columns operating together to produce a first antenna beam. At least a second array of antenna elements includes at least some other of the plurality of radiating elements on each one of the columns so as to operate together to produce a second antenna beam. As such, each of the three vertically arranged columns include at least some elements from both the first array and the second array.

Abstract: An array antenna with each antenna element in the array being physically tilted away from a base plane of the array. End antenna elements are tilted at a higher angle than regular antenna elements. The radiation pattern, the end antenna elements can provide coverage directly above the antenna array (i.e. at 90 degrees to the horizontal) for different electrical tilts.

Abstract: An omni-directional small cell base station antenna includes at least one array of a first frequency on a lower portion of the antenna, at least one second array of a second frequency on an upper portion of the antenna, and at least one third array of a third frequency on the upper portion of the antenna. The second frequency is higher than the first frequency, and the third frequency is higher than the second frequency. The at least one second array at a second frequency includes a plurality of reflector plates with antenna elements of the second frequency thereon, and the at least one third array at a third frequency includes a plurality of reflector plates with antenna elements of the third frequency thereon. The reflector plates of the at least one second array are interspersed between the reflector plates of the at least one third array such that the reflector plates of the second and third arrays alternate around the circumference of the upper portion of the antenna.

Abstract: Systems and devices relating to dipole antennas. The beamwidth of a crossed dipole antenna is widened by providing a parasitic monopole antenna adjacent to the crossed dipole antenna. In one configuration, each arm of the crossed dipole antenna has, adjacent to it, a parasitic monopole antenna. In another configuration, the crossed dipole antenna is surrounded by a number of other crossed dipole antennas acting as parasitic monopole antenna elements. The center or primary crossed dipole antenna can be for low band signals while the secondary crossed dipole antennas are for high band signals.

Abstract: A cellular antenna having at least one MIMO array has at least a first group of elements arranged in horizontal rows and vertical columns and at least a second group of elements arranged in horizontal rows and vertical columns. The first group and the second groups are arranged at least partially side-by side on said antenna. The elements of the first group are arranged in at least one vertical column of elements that is exclusive to elements of the first group. The elements of the second group are arranged in at least one vertical column of elements that is exclusive to elements of the second group. The antenna includes at least one separate common vertical column of elements, that includes elements of both said first group and the second group of elements.

Abstract: A multi-band generalized antenna architecture using two or more types of antenna element is presented. Linear arrays of a first type of antenna element are used for one or more frequencies while a second antenna element type is used for other frequencies. The second type of antenna element is located between the linear arrays of the first antenna element type. The second antenna element type may be arranged in a staggered configuration or they may be arranged as linear arrays as well. The first type of antenna element may be a patch antenna element while the second type of antenna element may be a dipole antenna element. The patch antenna element may be used for high band frequencies while the dipole antenna element may be used in low band frequencies. The spacing in vertical direction is not equal to minimize the effect of arrays on each other.
