This article presents experimental investigation on the effect of layer displacements for an X-band circularly polarized patch antenna. Experimental results demonstrate that such antenna makes use of high-low-low dielectric materials combination has tolerant characteristics not just on the impedance bandwidth but also the CP bandwidth to withstand layer displacements. Based on the measured bandwidths, displacement limits are located as 0.067 o for the entire x-y plane. Also, gain variations are found to be insignificant.
