Abstract
A Two dimensional passive Van Atta retrodirective array is proposed using dual port dual polarized microstrip square patch
antenna at a frequency of 2 GHz. The dual polarized microstrip antenna is designed using the aperture coupled feeding
technique. A parametric analysis is performed till reaching the optimum design which yields 7.4 dB peak gain, 140º half power
beam width. Full 3D EM simulation of the designed antenna array is performed. The Monostatic Radar Cross Section for the
proposed structure is presented. The double-substrate structure used enhanced the bandwidth of the antenna element by 41%
than previous references. The proposed array configuration achieved excellent cross-polarized monostatic RCS within ±55º
compared to other recent publications. In addition, the cross-polarized level of the array is easily distinguished from that of the
flat plate by greater than 30 dB.
Keywords: Aperture Coupled, Dual Polarized, Retrodirective, Van-Atta array.

Abstract
A Two-dimensional active Van Atta retrodirective 2x2 array is designed using dual port dual polarized microstrip square patch
antenna at a frequency of 2 GHz. The dual polarized microstrip antenna is designed using aperture coupled feeding technique in
a double-substrate structure. This structure facilitates the assembly of the RFIC amplifiers layer with the patch antenna layer. The
Monostatic Radar Cross Section for the proposed structure is presented. The proposed array configuration achieved excellent
cross-polarized monostatic RCS within ±55º compared to other recent publications. In addition, the cross-polarized level of the
array is easily distinguished from that of the flat plate by greater than 30 dB. The proposed structure promises enhancement in
the cross polarization level of the array.
