An apparatus includes a substrate and a plurality of antenna elements on the substrate and arranged according to an antenna configuration. The antenna configuration includes a rectangular antenna patch, and first and second pairs of circular antenna patches. The first pair of circular antenna patches supports a first angular polarization, wherein the circular antenna patches of the first pair are coupled to opposite corners of the rectangular antenna patch. The second pair of circular antenna patches supports a second angular polarization that is orthogonal to the first angular polarization, wherein the antenna patches of the second pair are coupled to opposite corners of the rectangular antenna patch, wherein each of the antenna patches of the first pair are positioned on corners adjacent to both of the antenna patches of the second pair.

Dual polarized base station and user equipment antenna for upper mid-band X-MIMO

An apparatus can include a substrate, a first antenna panel, a second antenna panel and a wall isolator. The first antenna panel can be coupled on the substrate and comprising an array of first antenna elements. The second antenna panel can be coupled on the substrate comprising an array of second antenna elements. The wall isolator can be coupled on the substrate. The wall isolator can include a first EBG element and a second EBG element. The first EBG element can be positioned along an edge of the first antenna panel for a length of the substrate and configured to reduce surface wave propagation from the array of first antenna elements. The second EBG element can be positioned along an edge of the second antenna panel for a length of the substrate and configured to reduce surface wave propagation from the array of second antenna elements.

Low-profile frequency-selective antenna isolation enhancement for dual-polarized massive MIMO antenna array

An apparatus includes a substrate, first and second transmission lines on the substrate, first antenna elements coupled to a first-first transmission line, and second antenna elements coupled to a first-second transmission line. A first distance between the adjacent first-first and first-second transmission lines is different than a second distance between the first-first transmission line and a second-second transmission line, the second-second transmission line adjacent to the first-first transmission line on an opposite side from the first-second transmission line. At least two antenna elements in the first antenna elements are differently sized.

Low-profile high-efficiency wide-scanning antenna array

An apparatus includes a substrate, a first antenna panel, a second antenna panel, and an antenna isolator. The first antenna panel is coupled on the substrate and includes an array of first antenna elements. The second antenna panel is coupled on the substrate and includes an array of second antenna elements. The antenna isolator is coupled on the substrate and including a plurality of walls extending outwardly from the substrate along a length of the substrate between the first antenna panel and the second antenna panel. The antenna isolator reduces reduce wave propagation between the array of first antenna elements and the array of second antenna elements.
