Abstract

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. Β© 2002 Wiley Periodicals, Inc.

The resonant frequency of a circular patch antenna with and without circular cavity is measured. The patch miniaturization in the presence of the cavity is proved. Different methods of reducing resonant frequencies and broadening bandwidth without significantly reducing antenna gain are presented. C
