The present invention relates to a hybrid antenna for easily receiving various kinds of radio signals including an FM signal with a simple configuration of combining a helical antenna and a loop antenna in a serial type. The hybrid antenna according to the present invention is constituted by combining one end of a helical antenna to a feeding part formed on a substrate, and combining a loop antenna with a fixed length to the other end of the helical antenna combined with the feeding part. The helical antenna is configured so that a coil with a thickness equal to or less than 1 mm is formed helically as having an external diameter of 20 mm, an internal diameter of 18 mm and an interval within 3 mm to have a length equal to or less than 100 mm. The loop antenna is configured to arrange a coil with thickness equal to or less than 1 mm so that loops with "�� shape from the top side and "T" shape from the side intersect up and down. |
