Abstract: A windmill-shaped loop antenna having a parasitic loop antenna is provided to implement an omni-directional small loop antenna pattern with a simple structure. A windmill-shaped loop antenna having a parasitic loop antenna(11) includes a dielectric substrate, a first radiating device, a second radiating device, and a plurality of feeding devices. The first radiating device is placed at the upper side of the dielectric substrate, and is composed of a windmill-shaped metal pattern which has loop pieces. The second radiating device is placed at the lower side of the dielectric substrate, and is composed of a windmill-shaped metal pattern which has loop pieces arranged not to face the loop pieces of the first radiating device. The plurality of feeding devices are connected on the same path from the center of the upper/lower sides of the dielectric substrate to the first and second radiating devices, and feed the first and second radiating devices in the same direction.

Abstract: A loop antenna is provided to reduce a length of a transmission path and to minimize a size of an antenna by installing an inductor on a transmission path. A loop antenna(200) includes at least one inductor(220). The loop antenna is formed by a conducting line. The inductor is installed on the conducting line. The loop antenna matches an input voltage value by separately adjusting an inductance value of the inductor. The inductor is installed on a point having the largest intensity of a surface current which flows on the conducting line. The inductor is installed on a part of a line which has a phase delay effect without having an influence on a radiation.
