PURPOSE: To provide the light in weight radio communication diversity antenna having a required antenna characteristic whose configuration is simplified more than a conventional antenna where antenna elements are made of a pipe and which are manufactured inexpensively.

CONSTITUTION: Conductor thin film patterns 11a, 11b for a 1st antenna 10 and conductor thin film patterns 12a, 21b for a 2nd antenna 20 are arranged on a strip shaped printed circuit board 4 along with its lengthwise direction. A 1st choke coil 14 is provided to a position where a leakage distribution of a 1st antenna use feeding cable 13 is maximized to block a leakage current of the 1st antenna and to attenuate a coupling current from the 2nd antenna 20. Furthermore, a 2nd choke coil 24 is provided to a position where a leakage distribution of a 2nd antenna use feeding cable 23 is maximized to block a leakage current of the 2nd antenna.
