7.It is demonstrated that changing parameters of the dipoleantenna is an effective method to adjust its resonant characteristics; the good reduced size can be achieved by properly altering its parameters; and the meander-line dipoleantenna are suitable for the application as RFID tag antenna.
8.Annexed impedance adopted to optimize dipoleantenna (DA) makes DA become ultra broadband antenna, which relative bandwidth ratio reaches 0.73. The designed shield resonance loop antenna (SRLA) holds better standing wave ratio (SWR), stronger ability to suppress interferences.
9.In this paper, resonant characteristics of the meander-line dipoleantenna depended on times of meanders, the height of meanders and the angle of meanders are analyzed.
10.The Poynting vector that represent the flow of electromagnetic power density on a sphere from a linear dipoleantenna is approximated by the summation of the field of segmented line current as Hertz dipoles.
