Abstract

In this paper, we propose the aperture feeding as a technique for bandwidth enhancement of multi-band microstrip ring antennas. In particular, we present a dual-band stacked annular-ring microstrip antenna fed by four bow-tie apertures with circular polarization. Furthermore, we show that the size and shape of the substrate that supports the radiating elements of the antenna plays an important role in the quality of the axial ratio.
