Abstract: The invention relates to a microwave antenna for flip-chip semiconductor modules, comprising two semiconductor substrates which are metallized on the surface thereof.

Abstract: An antenna element 1 is formed such that a plurality of turning parts 13, 15, 17 are formed by being turned back in zigzag in parallel to a ground conductor film 2 while extending perpendicularly thereto and the lengths of segments 12, 14, 16, 18 between the turning parts are shorter on a side of the ground conductor film 2 (a side of a feeding part 4) and increase gradually as the segments are away from the ground conductor film 2. The turning parts of the antenna element 1 are formed such that the antenna resonates at two or more frequency bands, and has a fractional bandwidth of 4% or more of its frequency in a first frequency band and a fractional bandwidth of 15% or more of its frequency in a second frequency band by adjusting the lengths L1, L2 and L3 of respective segments and the intervals d1, d2 and d3 between adjacent segments. Consequently, a wideband antenna is realized in two or more multi-frequency bands, for example 2.4 to 2.5 GHz and 5 to 6 GHz, by using a single folded antenna.

Abstract: It is desirable to make the antenna wiring more efficient in the building of an RFID system. The system includes antennas and readers connected in an arbitrary manner, in which calibration tags are installed on all the antennas. By reading the calibration tags, the system automatically generates the correspondences between the access paths and antenna logical names of the antennas, to serve as antenna configuration information. While the user generates combinations of the antenna logical names of the one or more antennas to be simultaneously driven, to serve as derive sequence information. The system compares the automatically generated antenna configuration information with the user-generated driving sequence information, and if there is an inconsistency in the setting of the both, generates an antenna rewiring procedure so as to resolve the inconsistency. The antenna rewiring procedure is generated as a combination of the substitution operation of the antenna wiring.
