Abstract: A stacked patch antenna comprising two metallic patches (210, 240) stacked on top of each other. The middle patch (210) comprises at least two conductors (224, 234) at or close to its edge (212), which conductors are intended to be connected to a ground plane (200) to thereby ground the patch in two places. The top patch (240) comprises at least two conductors (254, 264) at or close to its edge (242) which electrically interconnect the two patches. The middle patch is fed at a feed area (219) which is at least proximate its geometric center. The middle patch further comprises at least two apertures (220, 230) completely within its circumference (212), i.e. each aperture having a respective unbroken circumference (232, 242). Thereby enabling radiation from slots (214, 216, 244, 246) defined by the edge of the top patch and the edge of the middle patch and defined by the edge of the middle patch and the ground plane.

Abstract: An N-element rotational-symmetric array antenna can generate N fixed pencil-beams simultaneously with an omnidirectional beam. An N×N Butler matrix can be used to feed the array antenna, using fewer than N input ports of the Butler matrix to produce the pencil-beams. One or more of the modes generated by the Butler matrix can be individually accessed to produce one or more corresponding omnidirectional beams. The N×N Butler matrix can be driven by a feed network that provides both power dividing and beam-steering, which permits simultaneous generation of the N pencil-beams.

Abstract: A dual-polarized antenna (10) with good isolation between feed ports (13a, 13b) and high similarity with respect to the radiation patterns is provided. An antenna (10) includes a patch (11), four symmetrically arranged feed structures (12a-12d, 15), two feed ports (13, 13b) and a feed network (14). Radiation pattern similarity is obtained by the pair-wise symmetrical, orthogonal layout of the feed structures (12a-12d, 15). Good isolation between feed ports (13a, 13b) is achieved through a feed network (14) divided into two network parts (14a, 14b) where each network part (14a, 14b) is designed so that each coupling between a network part (14a, 14b) and a feed structure (12a12d, 15) belonging to the other polarization is cancelled by a mirrored coupling with the other feed structure (12a-12d, 15) belonging to the polarization. In addition, a network part (14a, 14b) is laid out so that its corresponding feed structures (12a-12d, 15) are fed with supporting signals of equal magnitude.

Abstract: An antenna arrangement includes a number of first radiating elements radiating in a first frequency band and a number of second radiating elements radiating in a second frequency band. The first and the second radiating elements are arranged in different planes. The second radiating elements are arranged in relation to the first radiating elements in such a way that each second radiating element partly overlaps the corresponding first radiating element. Each radiating element has at least one resonant dimension and the resonant dimension of the first radiating element is approximately twice the resonant dimension of the second radiating elements and the second radiating elements radiate at a frequency, or in a frequency band, which is approximately twice that of the first radiating element(s).
