A new stacked microstrip antenna structure that enhances the bandwidth without changing the resonance frequency is proposed and studied in this paper. The effect of the various antenna parameters on the bandwidth is investigated. The resulting antenna, using the proposed structure, has an ultra‐wide bandwidth of 35%, compared to 21.8% for the conventional stacked antenna structure. The proposed structure has little effect on the antenna's radiation characteristics. The analysis of the proposed structure is carried out using the FDTD method. © 2002 Wiley Periodicals, Inc.
