Abstract: An antenna element (100) comprises an active patch formed by a conductive layer (104) on a front surface of a substrate (102) and a parasitic ground patch (106) on a back surface of the substrate. The active patch has a spiral slot (112) in a central portion, and peripheral portions (110a-110d) which are substantially wider than the spiral slot. A signal feed strip (114) extends from a side of said active patch across the front surface of the substrate. Two signal ground strips (116, 118) are provided on the front surface, each separated from the active patch by a predetermined gap (120, 122). The parasitic ground patch has a slot in a central portion substantially back-to-back with the central portion of the active patch through the substrate. The element has broadband properties that can be tuned by various modifications. Several elements can be used in close array, with lower cross-talk than known antenna designs.

Abstract: The invention provides an antenna array comprising: a plurality of antenna modules, each of the antenna modules comprising an antenna, a signal conductor and one or more microelectromechanical (MEMS) switches, the antenna being conductively connected to the signal conductor, the MEMS switches and at least a portion of the signal conductor being supported by a MEMS substrate; and one or more integrated circuits comprising MEMS control circuitry configured to control the said one or more MEMS switches and/or signal processing circuitry configured to process signals received and/or to be transmitted by the antennas of the antenna modules, wherein the antenna modules and integrated circuits are supported by a common carrier substrate comprising the antennas of the antenna modules, the MEMS switches; or the said one or more integrated circuits. A hierarchy of MEMS controllers includes a master MEMS controller and local MEMS controllers which send control signals to a plurality of MEMS switches.
