• The design of miniaturized printed wire antennas using multilayer vias loaded periodic metallization is presented. The proposed structure is evolved from a periodic slow-wave transmission line, where each unit cell is made of a patch and two loops spread over two metal layers connected in series through vias. A section of the periodic metallization is used as a quarter-wave monopole antenna protruded over a truncated ground plane and fed by a microstrip line. The design prototype at 2.4 GHz band shows that it is possible to obtain 24% 10 dB bandwidth with 80% efficiency at an antenna length of 12 mm long without tuning inductors, more than a 50% reduction from a normal printed straight monopole.
