The invention relates to a loop antenna of digital radio receiver and a two-core cable capable of easily indentify each cable for receiving satellite wave or ground wave. An electromagnetic coupling type four-point feeding loop antenna comprising a tubular body formed by twisting flexibility insulation film part with center shaft (O) and a loop portion formed reeling the center shaft and along circumference of the tubular body. The four-point feeds power to the loop portion, setting four feeder on circumference of the tubular body. Setting a gap (delta) between the loop portion and feeders, feeding power to the loop portion by electromagnetic coupling. Moreover, connecting eight electromagnetic coupling wires of each feeder clamping from two sides to the loop portion to form the gap as comb, or the loop portion includes a extension part paralleling with the centre shaft (O) and bending over one side of feeding power source and extending, or one cable of a pair cables for composing the two-core cable, formig a vertical extended upward wire on surface of outside insulating layer. |
