Abstract

PURPOSE:To make it possible to match the impedance without moving the position of the feeding points, by forming a slit passing between the feeding points, on the electric loop conductor of a loop antenna. CONSTITUTION:The feeding points 4a, 4b are connected to the load 6 through the feeders 5a, 5b. Desired positions of the slit 7 are short-circuited by use of a short- circuit piece 8 by forming the slit 7 passing between the feeding points 4a, 4b, on the electric loop conductor 1. In this way, a current flowing between the feeding points 4a, 4b on the electric loop conductor 1 flows as a loop along the slit 7, and the impedance can be matched by the positions of the short-circuit piece 8.
