A dual‐band circularly polarized stacked elliptic microstrip antenna

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.
