Abstract
Abstract In a micro-strip antenna comprising a radiating conductor and a grounding conductor which are installed on either side of a dielectric, a plate-form conductor is attached to the radiating conductor at a position which is roughly at point where an extension line extended from a line, that connects the center of gravity of the radiating conductor and a feeding point, intersects an edge of the radiating conductor. The plate-form conductor is attached also at a position which is rotated 90 degrees about the center of gravity from the above-described position. In addition, a portion of the plate-form conductor is set to project from the edge of the radiating conductor. In this way, the center frequency of the micro-strip antenna can easily be corrected during the manufacturing process of the micro-strip antenna.
