An electronic device according to various embodiments of the present invention may comprise: a body which is made of a conductive material and has both ends curvedly extending to be adjacent to each other so as to have a loop shape; a communication module arranged on the body; a feeding line which extends from the communication module and is arranged to cross a gap between both ends of the body; and at least one connection terminal for connecting the feeding line to the body, wherein the body can receive a feeding signal from the communication module through the feeding line, and transmit/receive a wireless signal. The above-mentioned electronic device can be implemented variously according to embodiments.

Electronic device including loop-shaped antenna

A method for operating a large scale antenna array in a wireless communication system includes receiving one or more signals. The one or more signals include information for beamforming to a plurality of user equipments (UEs) using a full-dimensional multiple-input multiple-output (FD-MIMO) beamforming scheme. The FD-MIMO beamforming scheme includes same time resources and same frequency resources that are co-scheduled to the plurality of UEs. The method further includes identifying a time delay of the one or more signals associated with one or more antenna arrays that are distributed in the large scale antenna array and performing a multi-user (MU) joint beamforming on the one or more signals to one or more UEs.

2D active antenna array operation for wireless communication systems

A base station (BS) capable of communication with a number of transmission points includes a processor configured to control a beamforming transmission or reception and an integrated antenna array system. The integrated antenna array system includes a baseband signal processing unit configured to perform baseband functions and disposed between the two sections. The integrated antenna array system also includes a plurality of physical antenna elements disposed in groups. Each of the groups includes an equal number of the plurality of physical antenna elements. The plurality of physical antenna elements are disposed symmetrically around the baseband signal processing unit.

Integrated two dimensional active antenna array communication system

A transmitter includes apparatus for integrating the antenna feed into a multilayer PCB. The apparatus includes an antenna element disposed over the multilayer PCB having slot openings that substantially overlap and that enable an RF signal to be coupled from a printed transmission line located on one of the multilayer PCB conductive layers. The multilayer PCB board hosts at least one transceiver unit and a baseband unit such that the antenna feed, transceiver and baseband units are integrated on a single multilayer PCB board without degradation of antenna bandwidth and efficiency.

Antenna feed integrated on multi-layer PCB

In a Multiple Input Multiple Output (MIMO) system, an apparatus and method includes a Tightly Coupled Array antennas (TCA) or Current Sheet Antennas (CSA). Far-field radiation patterns from any current sheet antenna are formed from the combination of the fields generated by a set of currents on the CSA of array port orthogonal modes, such as the Characteristic Modes (CM). The CM currents are generated by excitation of the CSA element ports with corresponding orthogonal voltages or currents (eigenvectors). Since the radiation patterns of the characteristic modes are orthogonal and uncorrelated, multiple signals may be propagated along the radiation patterns of the characteristic modes, each signal using a different characteristic mode or a different set of characteristic modes. Therefore, a CSA antenna utilizing array port orthogonal modes such as array port characteristic modes can support MIMO communications despite the strong mutual coupling among the antenna elements.
