Abstract

The paper presents a novel design of planar multilayered microstrip antenna arrays using aperture-coupled stacked patch radiating elements with dual polarization capability. Frequency bandwidth of up to 26% (VSWR < 2:1), isolation between orthogonally polarized channels better than 30 dB 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 measured characteristics of a manufactured antenna samples, operating in frequency bands from 0.9 to 15 GHz.
