Printed elements antennas "Patch" have the advantages of microstrip lines, light weight, reduced by the technique of printed circuit cost. They can be placed on land or space vehicles, easy to networks of tens or hundreds element, connected directly to the power supply device that goes in the direction of integrating the antenna and power supply. Diet plays a very important role in the design of patch antennas. It can be made by direct connection to a microstrip line which is the junction point on the axis of symmetry of the element or offset with respect to this axis, or by direct connection to a coaxial line whose central conductor is connected at a point on the axis of symmetry of the element.
