Abstract
An antenna which reduces the number of end faces and perpendicular corners, and suffers from little deterioration of performance even if used for high frequency transmission/reception, in particular a microstrip patch antenna which is comprised of a dielectric substrate on the bottom surface of which a conductive ground plate is formed and on the top surface of which a patch antenna part formed by a conductor and a feeder circuit connected to the same are provided, wherein the feeder circuit is connected to the antenna part while offset by exactly a predetermined distance to either end side from a center of one side of said antennas part to which said feeder circuit is to be connected so that a transmission loss of the antenna becomes a predetermined value or less. The predetermined distance can be made 20 to 70% of the longitudinal side of the patch antenna part.
