Design of duality array of dielectric embedded patch Yagi antenna

The three-dimensional dielectric embedded patch Yagi antenna is created by reducing the periphery of microstrip patch antennas´ grounding deposited copper(but never change the size of the substrate), superimposing its substrate layer after layer and depositing the copper element (driven element and director element) in appropriate thickness place of the cascading substrate. The three-dimensional duality array of dielectric embedded patch Yagi antenna is composed by the two antennas. This design of cascade embedded group array is reasonable. It has been proved by simulation and practical antenna testing.
