    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: An antenna producing a quasi-omni radiation pattern. The antenna includes at least three main panels, each having a plurality of radiating elements thereon, disposed in one or more columns of elements. The main panels are disposed in a substantially circular arrangement to generate the quasi-omni radiation pattern. At least one null filling panel is disposed between every two consecutive main panels of the at least three main panels, directed towards a null in the quasi-omni radiation pattern between the two consecutive main panels. The null filling panel has at least a single column of elements that radiate a null filling signal that is substantially the same signal as a signal from elements from the two adjacent main panels.

    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 remote radio head assembly attaches a remote radio head to the back wall of an antenna unit. The remote radio head assembly has a radio bracket attached to the top of the radio head having a handle for lifting and carrying the radio head. Radio guide spacers attached to the back side of the remote radio head are for sliding the remote radio head along a mounting rail attachment disposed on the back wall of the antenna unit. The mounting rail has a pivot hook for receiving an installation lever configured to engage with the handle to move the remote radio head in downward and upward directions so as to couple the connector ports of the antenna unit.

    Abstract: In a dipole antenna, a capacitive coupling element is introduced in the form of a conductive strip and is placed in parallel with the dipole conductive strip of the dipole arm. To that end, the conductive strip of the capacitive element is formed on a first copper layer of the PCB in parallel to an extended conductive strip of a dipole arm, that is also disposed on the first copper layer of the PCB. The conductive strip of the capacitive element extends horizontally from the center of the dipole arm in an equal distant on each side. A capacitive plate is placed on the second copper layer of the PCB on the opposite side of the first copper layer and is coupled to the conductive strip of the capacitive element via a plated through hole. The capacitive plate placed on the second copper layer extends downwardly so that a portion of it overlaps with the dipole conductive strip located on the first copper layer forming the capacitance coupling element.
