Abstract
A patch radiator antenna is described including a sheet of conductive material and a dielectric substrate having a first and second surface, the sheet of conductive material disposed upon the first surface of the dielectric substrate. The patch radiator antenna further includes a plurality of patch radiator elements disposed upon the second surface of the dielectric substrate, each one of the plurality of patch radiator elements having sides with a width and a length. The plurality of patch radiator elements include a first patch radiator element having a feed probe to couple the first patch radiator element to an RF signal source and at least one second patch radiator element including a microstrip feed along the width of the patch radiator element, the at least one second patch radiator element disposed fore of the first patch radiator element. The patch radiator antenna further includes a strip conductor having a first end and a second end, the first end connected to the microstrip feed and the second end connected along the length of the first patch radiator element. With such an arrangement, a corporate feed for each patch radiator element is eliminated, thus reducing feed lin…
