The normal mode helical antenna (NMHA) is widely used on RFID applications because it fits well with the requirements of smaller physical size and high inductive impedance. In this paper, a power transmission coefficient method of mapping a modified impedance function onto the conventional Smith chart is applied to conjugate matching design between NMHA and chips. Moreover, the effect of various geometrical...
RFID is applied to goods management, vehicle management, and medical equipments. The appliances of smart home are very popular today. To apply ICT (Information Communication Technology) to life is a popular study. People sometimes forget to take something away. He may take his laptop away, but forgets the battery or his mouse.
