Abstract:
An antenna structure comprising:a first antenna including a conductive patch; anda second antenna adjacent the conductive patch wherein the second antenna defines a central axis, wherein the central axis is orthogonal with respect to the first antenna, and wherein the central axis intersects a central portion of the conductive patch;wherein the conductive patch includes an opening therethrough and wherein the second antenna includes a feedline extending through the opening through the conductive patch;wherein the first antenna further includes a dielectric layer with the conductive patch thereon and with the opening extending through both the conductive patch and the dielectric layer and with the feedline for the second antenna extending through the opening through both the conductive patch and the dielectric layer; andwherein the feedline for the second antenna comprises a coaxial feedline including a central feedline and an outer groundline wherein the outer groundline is electrically coupled with the conductive patch at the opening therethrough.
