Abstract: An antenna array with control circuitry placed at a front of the antenna array and between the antenna elements. By locating the azimuth beamforming network control circuitry on the front of the array and between antenna elements, the antenna elements and the other components can be coupled to the control circuitry without using cables. This leads to a reduction in the number of cable connections and to a reduction in size and weight of the resulting antenna array. The ABFN control circuitry is also used to control the beams formed from each row and not from each column as is usually done.

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.

Abstract: Systems, methods, and devices relating to an antenna element and to an antenna array. A three level antenna element provides wideband coverage as well as dual polarization. Each of the three levels is a substrate with a conductive patch with the bottom level being spaced apart from the ground plane. Each of the three levels is spaced apart from the other levels with the spacings being non-uniform. The antenna element may be slot coupled by way of a cross slot in the ground plane. The antenna element, when used in an antenna array, may be surrounded by a metallic fence to heighten isolation from other antenna elements.
