Abstract
This paper presents a simple broad band printed Yagi Uda antenna operating at a resonant frequency of 400 MHz that can be used for Ultra High Frequency (U.H.F) applications like Radio Frequency Identification (R.F.I.D) Systems. The antenna is horizontally polarized and consists of a dipole, a reflector and a set of three directors which are placed 3 m above the ground. The impedance bandwidth of the proposed antenna is about 21.5 % and the maximum gain in the pass band frequency range is 16.3 dB with a return loss of -19 dB. The design formulas and various antenna parameters like Return loss, Voltage Standing Wave Ratio (V.S.W.R), Input impedance, Gain etc of the proposed antenna is observed and the simulation is carried out using an electromagnetic simulation tool , CADFEKO. The results show that the designed antenna is well suited for Ultra High Frequency applications like RFID systems.
