metal based material 16 g onto the der material 12 g an electrical device not shown may be attached to pads 28 a and simultaneously electrically connected to the der electrodeposit loop by techniques discussed in conjunction with fig1 through 15 material 16 g now forms a highly conductive low profile loop antenna inductor to transmit information and or power an electrical device not shown attached at pads 28 a such an antenna is substantially flat simple to mass produce and physically and electrically robust such an antenna would be very suitable for production of low profile items such as a contactless u201c smart card u201d or rfid tag fig1 through 23 illustrate a method of inexpensive mass production of a form of the low profile loop antenna introduced in fig1 through 18 in fig1 a web of substantially planar structure is identified generally as 39 structure 39 has a length in the direction designated by the letter u201c l u201d and width designated by the letter u201c w u201d in the embodiment of fig1 length u201c l u201d is contemplated to be considerably larger than width u201c w u201d and thus structure 39 can be processed in roll to roll fashion structure 39 fig1 is characterized by the following factors electrically insulating sheet 14 h supports a pattern of der electrodeposit composite material 12 h 16 h having multiple loops 40 a 40 b 40 c similar to those taught in conjunction with fig1 through 18 loop traces 40 a 40 b 40 c include mounting pads 28 b u201c buss.
