Abstract

In this paper, the miniaturized tag antenna which is composed of the folded dipole for UHF band is proposed. The reactance component of tag antenna considered chip impedance is conjugated and matched for maximum power transmission. The antenna is fabricated by using FR-4 dielectric substrate with permittivity 4.6. The size of antenna is 50 times 40 times 1.6 mm. The radiation pattern is good agreement with half wavelength dipole antenna. The dimension of antenna is externally reduced 61.7% than proposed antenna at references [4], [5]. The evaluation of tag antenna is processed by connection of 50 Ohm port. The results of RCS measurement present also that the power of tag antenna with chip is operated at 910 MHz compare with tag antenna without chip.
