A novel design of a probe‐fed stacked microstrip antenna for obtaining dual‐band circular polarization (CP) radiation is presented. By properly selecting two elliptic patches of different axial ratios in the proposed design, and introducing a small air‐gap layer between the two patches, dual‐band CP radiation can be obtained by exciting the top elliptic patch using a single probe feed. Details of the proposed antenna design and experimental results for the obtained dual‐band CP performances are presented and discussed. ©2000 John Wiley & Sons, Inc.
