BOOSTER ANTENNA AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide: a booster antenna that has excellent electrical characteristics and flexibility and permits inexpensive mass production; and a method of manufacturing the booster antenna.SOLUTION: A booster antenna 14 is manufactured by applying a silver particle dispersion liquid containing 50-70% by mass of silver particles having an average particle size of 20 nm or less to a substrate by flexographic printing, followed by firing. The booster antenna 14 has on the substrate a silver conductive film containing a sintered body of 10-50% by volume of silver particles and having a volume resistivity of 3-100 μ&OHgr; cm, a surface resistivity of 0.5 &OHgr;/sq. or less and a thickness of 1-6 μm.
