An antenna may be formed from conductive regions that define a gap that is bridged by shunt inductors. The inductors may have equal inductances and may be located equidistant from each other to form a scatter-type antenna structure. The inductors may also have unequal inductances and may be located along...http://www.google.de/patents/US8044873?utm_source=gb-gplus-sharePatent US8044873 - Antennas with periodic shunt inductors
