In a loop antenna of this invention, a plurality of segments are arranged in a loop while overlapping each other at end portions, a dielectric medium is inserted between the overlap portions of the segments to capacitively couple the segments, and a feed circuit is connected to at least one of the segments. The nodes may be ordered based on a criticality of the nodes that may aid in identifying those nodes of the circuit where hold time violations may be corrected. The supply regulation circuit also includes an adjustment circuit controlled by the control circuit and configured to adjust the regulated voltage according to the reference voltage. The second thinned region defines one or more flexure mechanisms configured to make the first thinned region and the first thick region movable relative to the second thick region in a direction parallel or substantially parallel to the polishing surface.
