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: Adjustable broadband impedance matching circuits using tapered lines A self-adjusting broadband impedance transforming circuit for matching a load port 4 to a source port 2 comprises a tapered transmission line 10 and at least one variable impedance 12 coupled to the line and adjustable by a controller 20 in dependence on the output of an impedance mismatch detector 21. The controller may access a look-up table to find initial adjustable impedance settings for a given signal frequency, the controller then providing fine adjustment in conjunction with the mismatch detector 21. The variable impedances may comprise semiconductor varactors, MEMS varactors, MEMS switched capacitors, ferroelectric capacitors, a bank of switched MEMS capacitors, or PiN diodes. The mismatch detector 21 maydetect voltage level, phase, or power. The variable impedances may be connected to the line, to its ends ( figure 3) or between line sections ( figure 4), and may be connected via stubs ( figures 8 and 9). The tapered line may comprise multiple short sections of constant width.
