PROBLEM TO BE SOLVED: To provide a configuration suitable for carrying and to prevent damage by making the height of antennas into low profile at the time of rod antenna housing by combining a magnetic current loop antenna and a flexible rod antenna. SOLUTION: A magnetic current loop antenna 11 and a rod antenna 12 are attached through an insulating member to a casing 1 of portable radio equipment. The magnetic current loop antenna 11 is constituted by winding the conductor wire of length corresponding to 1/2 to 1 wavelength in the shape of coil. Besides, one end 11a of the conductor wire is fixedly arranged at the upper part of the easing 1 of the portable radio equipment and connected to a transmission/reception circuit inside the portable radio equipment and power is fed. The rod antenna 12 is composed of a length corresponding to 1/4 to 1/2 wavelength. Besides, this antenna is provided on the central axis of loop of the magnetic current loop antenna 11, flexibly disposed on the casing 1 of the portable radio equipment, connected through a metal fitting 2 for power feeding, which is provided in the easing 1, and power is fed.
