| Abstract: | The small electrical antenna is characteristic of a low input impedance and a low efficiency. The input impedance can be efficiently increased by the double faced overlapped printing circuit and the small grounded coil .On the basis of the increased impedance, a good match can be realized in 4 MHz bandwidth (center operation frequency is 135MHz) by choosing the characteristic impedance and length of a segment of transmission line. |

| Keywords: | printing antenna grid model input impedance matching azimuth plane cover |
