A broadband, contiguous stacked, two-layer, square microstrip patch antenna element design is described which can be used for a linear or circular polarization. Single layer microstrip patch theory for the rectangular patch radiator is presented and used as a basis for understanding the two-layer patch configuration. The theory is modified to predict radiation patters and resonant frequencies of the two-layer microstrip patch antenna element. Experimental results include the radiation patterns, dominant resonant frequencies (TM10 mode), return loss (S11), and bandwidth for X band elements as a function of dielectric constants, dielectric thicknesses, and patch sizes.
