Abstract

The paper presents a novel design of a Ku-band (10.95-14.5 GHz) planar multilayered microstrip antenna using aperture-coupled stacked patch radiating elements with dual polarization capability. Frequency bandwidth of up to 26% (VSWR<2:1) and level of cross-polarization better than -30 dB have been achieved in both E- and H-planes of radiation pattern for the two orthogonal linear polarizations. Numerical results obtained by FDTD computer simulations are compared with experimentally determined characteristics of a manufactured antenna.
