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: A mobile terminal includes a display, a side frame, a back cover and an antenna. The antenna includes a conductive support and a feeding part. The conductive support includes a first portion and a third portion disposed opposite to each other, and a second portion and a fourth portion disposed opposite to each other. The four portions are made of conductive materials and jointly enclose a cavity. The second portion is disposed on an inner side of the display. The third portion is a part of the side frame. The fourth portion is located on an outer side or an inner side of the back cover, or is a part of the back cover. A gap is disposed between the fourth portion and the first portion, or is disposed in the fourth portion, and the antenna can radiate electromagnetic wave signal through the cavity and the gap.
