ABSTRACT:
A loop antenna unit (2), a balanced line (3), and two perturbation elements (4) are formed on a dielectric board (1) by using manufacturing methods, such as printing and etching. The loop antenna unit (2) is formed along the circumference of a circle, and is connected to the balanced line (3). Each of the two perturbation elements (4) is a member in the shape of a tooth which is inclined 45 degrees against a direction of feeding of power via the balanced line (3) and which is projecting from the loop antenna unit (2) in an inward direction toward the center of the loop antenna unit (2). The two perturbation elements (4) are arranged at two opposite points in the loop antenna unit (2) so that they are opposite to each other.
