Abstract
A method of manufacturing a micro-strip antenna in which when a radiating conductor is installed on one side of a dielectric which has a grounding conductor on another side. A projection is installed at an edge portion of the radiating conductor and cut a specific amount so as to adjust the center frequency of the micro-strip antenna. Instead, such an adjustment of the center frequency of the micro-strip antenna is obtained by cutting away a part of an edge area of the radiating conductor a specific amount.
Claims2
A method of manufacturing a micro-strip antenna characterized in that a projecting portion projected from an edge of a radiating conductor is formed substantially at a point where an extension line, that extends from a line which connects the center of gravity of a radiating conductor and a feeding point, intersects an edge of said radiating conductor, or at a point where a line, that crosses said extension line perpendicularly at said center of gravity, intersects an edge of said radiating conductor, and a center frequency of said micro-strip antenna is adjusted upwardly by cutting said projecting portion a specific amount.
A method of manufacturing a micro-strip antenna characterized in that a square or circular radiating conductor is installed on one side of a dielectric which has a grounding conductor on another side to provide a micro-strip antenna having a center frequency lower than desired and a projecting portion is provided on said radiating conductor at a point where an extension line that extends from a line which connects a center of gravity of said radiating conductor and a feeding point, intersects an edge of said radiating conductor, or at a point where a line that crosses said extension line at said center of gravity, intersects an edge of said radiating conductor, and said center frequency of said micro-strip antenna is adjusted upwardly to said desired center frequency by cutting said projecting portion.
