This invention concerns a multibeam antenna with adjustable pointing, comprising a single reflection arrangement and a plurality of radiating sources arranged opposite the reflection arrangement and suited to emit and/or receive radiofrequency (RF) signals, the reflection arrangement defining a centre, a focal plane, and a focal point located on the focal plane. The antenna is characterised in that at least one of the radiating sources (‘mobile source’) is movable substantially independently of the or each other radiating source on a scanning surface to adjust the pointing of the antenna, wherein the scanning surface coincides with the focal plane or is tangential to it at the focal point.

A variably controlled stagger antenna array architecture is disclosed. The array employs a plurality of driven radiating elements that are spatially arranged having each radiating element or element groups orthogonally movable relative to a main vertical axis. This provides a controlled variation of the antenna array's azimuth radiation pattern without excessive side lobe radiation over full range of settings.

A method of tuning an electrically small antenna comprising a radiating element and a support structure comprises applying a force to the support structure to change a shape or a dimension of the radiating element to increase or decrease a frequency at which the electrically small antenna resonates.

Parasitic element control apparatus and method for a single radio frequency (RF) chain-based antenna array. The apparatus includes an arranger configured to arrange antenna elements, each including a single active element and a plurality of parasitic elements, and generate an antenna structure, a designer configured to design a control parameter for controlling the parasitic elements based on the antenna structure, and an adjuster configured to adjust the parasitic elements based on the control parameter.

An antenna using a liquid metal is provided. The antenna includes a plurality of antenna structures, each having an inner cavity of a form corresponding to a radiator pattern; and at least one actuator connected to at least two of the plurality of antenna structures to control movement of the liquid metal to supply the liquid metal to at least one of the antenna structures. Thereby, deterioration of an antenna performance due to an influence of a human body can be prevented, and deterioration of an antenna performance can be prevented due to a form change of an electronic device including the antenna. In this manner, optimal antenna radiation performance can be dynamically realized.
