摘要： A cellular antenna is provided with at least a first array of elements arranged in horizontal rows and vertical columns and at least a second array of elements arranged in horizontal rows and vertical columns. The first group and the second arrays are arranged at least partially side-by side on said antenna. The elements of the first array are arranged in at least one vertical column of elements that is exclusive to elements of said first array. The elements of the second array are arranged in at least one vertical column of elements that is exclusive to elements of the second array. The antenna includes at least one separate middle vertical column of elements, between the at least one vertical column of elements that is exclusive to elements of said first array and the at least one vertical column of elements that is exclusive to elements of the second array. The middle vertical column of elements includes some elements in the first array and some elements in the second array.

摘要： 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.

摘要： 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.

摘要： 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.
