Furthermore, the X-direction antenna group 22 0A and the Y-direction antenna group 220B respectively include N/4 sets of X-direction antenna circuits 230A and M/4 sets of Y-direction antenna circuits 23 0B. In addition, each set of X-direction antenna loop 230A and Y-direction antenna loop 2 3 0B includes four antenna loops 235 A and 2 35B, so that the antenna loops can be arranged on both sides of the board. Therefore, the total number of antenna loops 235A of the N/4 group X-direction antenna loop 230A is N, and the total number of antenna loops 235B of the M/4 group Y-direction antenna loops 2 30B is Μ.

The first comparison program 245 compares the maximum voltage amplitude of the signal of the loop back of the strip antenna with the magnitude of If = under the signal recognition level. Then, each antenna loop is sequentially turned on and the first global scanning program 240 and the first comparison program 245 are repeatedly performed until all N antenna loops 235A of the X-direction antenna group 22 0A are turned on once. And obtain the voltage amplitude of N signals. After the voltage amplitudes of the N signals are compared with the signal: the lower limit of the identification level, the number value χρ of the antenna loop having the maximum voltage amplitude greater than the lower limit of the signal recognition level is recorded in a register χ_. If the signal amplitude value of any of the antenna loops is greater than the signal recognition level lower limit value, then the first global scan program 240 and the first comparison program 245 are repeatedly performed until the maximum voltage amplitude is greater than the signal recognition level lower limit.
