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: Systems and devices relating to antennas and antenna systems. A horizontal omnidirectional antenna has two dipoles with each dipole being in a V-configuration such that the arms of the dipole define an angle. The two dipoles are arranged so that the angles defined by each of the dipoles face and open toward each other. The horizontal omnidirectional antenna can be configured to operate with specific frequency bands. By nesting two instances of this antenna, with one configured for high band frequencies and one configured for low band frequencies, a dualband omnidirectional antenna can be obtained. The resulting antenna is physically compact and can be used in small MIMO systems along with vertical omnidirectional antennas.

Abstract: A dipole antenna array element using crossed dipoles is provided. The arms of the crossed dipoles are spaced apart from a ground plane. The length of the arms of the crossed dipoles, as well as the height of the array element, is dependent on the lowest wavelength of signal for which the element is to be used with. To adjust the impedance of the antenna array element, a strip of conductive material is used to enclose an area about the arms of the dipoles. A patch component can also be used with the arms being between the patch component and the ground plane.
