To overcome this problem, a ground plane needs to be inserted into that antenna design, so that the metallic surface effect can be reduced [15]. However, adding the ground plane alone to that antenna design does not give any better result at all. The design of the tag antenna needs to be adjusted in order to get optimum results. Several steps have been carried out to redesign the previous tag antenna design. The first step is by adding rectangular loop with the dimension of 60 x 43 mm and the width of 5.5mm as shown in Fig. 3(a). Adding the loop without connected it to the original tag antenna design only can increase the imaginary part of the antenna impedance but it does not give any improvement to the S-Parameter result as the loop only act as a parasitic element
