Design of a 2D Planar Sensor Antenna for Localization of RFID Tag

Abstract

Localization and orientation of search coil is presented. Localization of planar antenna with eight coil design was demonstrated in various researched papers. Application based on localization are virtual bronchoscopy system, tracking of eye and others. These eight coils were employing with different frequency range from 3-100khz. For the excitation of eight coils different feeding port had been used. This problem can resolved by using only single frequency which ultimately minimizes the number of feeding port. Using time division approach instead of frequency division approach, better results has achieved by using the switching network for the same eight array coil but with different approach . While comparing the initial approach with our proposed approach , the postion and orientation error results are more in frequency division approach. From analysis results, it is observed that our proposed approach having 60% of accuracy in results whereas only 30% is observed in the initial approach.
