Abstract
A printed antenna includes a dielectric substrate having a pair of printed antenna elements to form a dipole antenna. On an antenna plane, an xy axis system is defined so that an origin is defined at a center of location of the antenna elements, and an x axis is set in a direction that the antenna elements are arranged, a y axis is set in the direction perpendicular to the x axis, and a size of the antenna elements in the direction of the y axis become gradually larger according to the x axis changing in an outer direction. Each of the antenna elements has an impedance matching part at a feeding side of the antenna elements. The printed antenna can be used in an ultra wide-band frequency, and is small profile, is light weight and low in cost.
