Abstract: An antenna assembly, an apparatus having the antenna assembly, and a method of manufacturing the antenna assembly are disclosed. Antenna performance in, e.g., mobile devices is improved via an antenna assembly which allows wide-angle beam scanning across a wide frequency bandwidth. Wide beam coverage may in turn contribute to improving multi-surface spherical beam coverage, such as in broadside direction and endfire direction, and to reducing the amount of needed antenna modules. A tightly-coupled dipole array exhibits wide operating frequency bandwidth characteristics.

Abstract: An electronic device comprises a housing having a first side and a second side, a dielectric cover (602) on said second side, and an electrically conductive peripheral structure along edges of said first and second sides. An antenna feed (601) is coupled to a portion (603) of said peripheral structure for using said portion (603) as a radiating antenna element. A conductive member (604, 804) is located on or underneath said dielectric cover (602). The purpose of the conductive member is to enlarge the surface area where the electric field is distributed on to increase the antenna aperture for radiation.

Abstract: A millimeter-wave antenna arrangement (1) comprising at least one first antenna array (2), said first antenna array (2) comprising a plurality of antenna elements (2a) such as patch antennas, and an artificial dielectric structure (3) superposed over said first antenna array (2). Said artificial dielectric structure (3) comprises a plurality of conductor layers (4) separated by dielectric layers (5), each conductor layer (4) comprising a plurality of periodically repeated conductor patterns (6). One conductor pattern (6) of each conductor layer (4) is associated with one of said antenna elements (2a), and the conductor patterns (6) associated with one antenna element (2a) are at least partially non-identical. Said artificial dielectric structure (3) has an artificial dielectric constant, and each dielectric layer has a natural dielectric constant, said artificial dielectric constant depending at least partially on the natural dielectric constants and preferably having a value between 10-30.
This configuration provides a way of achieving multi-surface beam coverage, e.g. by means of end-fire antenna elements as well as broadside antenna elements, while maintaining a compact footprint.-

Abstract: An electronic device and antenna system for generation of millimeter-wave frequency radiation. The antenna system has first conductive structure, a second conductive structure, and an antenna comprising a first antenna element configured to excite a first electric field having a first polarization, and a second antenna element configured to excite a second electric field having a second polarization. The first antenna element and the second antenna element extend in an antenna plane. An anisotropic dielectric volume is partially enclosed by the antenna, the first conductive structure, and the second conductive structure. A first surface of the dielectric volume is open to the exterior of the antenna system. The dielectric volume allows the first and second electric fields to propagate, within the dielectric volume, from the antenna at least partially towards the first conductive structure, and to radiate from the first surface to the exterior.

Abstract: An antenna arrangement is described. The antenna arrangement comprises an antenna array that includes a first antenna element having a first feed point, and a second antenna element having a second feed point. The antenna arrangement further comprises a signal processing device configured to receive an input signal (Sin), obtain a first complex weight (w1), obtain a second complex weight (w2), generate a first feed signal (a1) based on the input signal (Sin) and the first complex weight (w1), generate a second feed signal (a2) based on the input signal (Sin) and the second complex weight (w2), provide the first feed signal (a1) to the first feed point, and provide the second feed signal (a2) to the second feed point so as to control the frequency characteristic of the antenna array. A method for such an antenna arrangement is also described.

Abstract: A redirecting structure for electromagnetic waves, the redirecting structure comprising a first reflection passage formed between a first conductive element and a second conductive element, and an antenna structure comprising an antenna element and a radiation passage extending from the antenna element in a first direction. The antenna structure is connected to the first reflection passage at a first interface, the first reflection passage extending in a second direction different from the first direction. A first reflective structure is associated with an interior of the first reflection passage and is arranged at a predetermined distance from the first interface such that electromagnetic waves propagating from the antenna structure into the first reflection passage are reflected to the radiation passage by the first reflective structure.
