The Study for the Dipole Antenna in Tag;

A novel planar four unit cells dipole antennas based on composite right/left handed transmission line and loaded periodically with shunt inductors and series capacitors was constructed in this study,which features reduced wavelength with decreasing frequency of antenna.

Since the demand for flexible RFID(radio frequency identification) antennas with higher efficiency has increased in the recent years,an overview of λ/2 dipole antennas design for passive RFID tags was presented.

rank-1 ambiguity) problem associated with the polarization-angular coherence structure (PACS) of a tripole antenna by defining a new coordinate system where the two signals of concern both lie in the same coorainate plane, along with a theoretical demonstration indicating that the involved coordinate rotation has no effect on the study of the problem under consideration.

In this paper firstly the corona pulse current is theoretically researched; then the electromagnetic radiation field caused by corona pulse current is calculated by use of short dipole antenna model; finally the influence of different voltage class on electromagnetic radiation field and electr.

Because of having broad bandwidth and no electrical wires leading outside of the embedded signal source,the spherical dipole antennas have wide applicability in EMC test.
