The power strength of electric wave of reader looked radiation forms from the gate type RFID system. The more distant from antennas, the weaker of power strength of electric wave. The power strength of electric wave with 3 antennas showed stronger than its with 2 antennas. With 2 antennas, the coefficient of correlation between the power strength of electric wave and response ability of tag was 0.665 (p=0.009), and it showed results at significance level. With 3 antennas, the coefficient of correlation was 0.711 (p=0.004), correlationship between the power strength of electric wave and the response ability of tag showed at significance high level. From the analysis result about tag reading performance on the gate type RFID system, the reading rate was good when tags were attached on a acrylic plate which were located in front of 3 or 4 antennas. As tags were getting away from antennas, the reading rate was decreased. The nearer from antennas, the higher the reading rate at the center. When tags were turned at right angles with antennas, the longer distant from antennas, the lower reading rates at the center, right and left locations. When the number of antennas and distance are constant, respectively, the significant difference of the tag reading rates according to the locations of left, right and center were not found.
