Abstract

A dual band, dual diversity Sierpinski gasket antenna with two feed ports and a single band, triple diversity rectangular patch antenna with three feed ports are presented. The significance of the antennas is that they can provide dual signal diversity for communication systems at two different frequency bands or three branch diversity for single frequency operation. Experimental results are presented for the designs that operate at 1800MHz and 3900MHz for the gasket and 3400MHz for the patch. Experimental results include S-parameters and envelope cross-correlation coefficients so that diversity performance can be demonstrated. FDTD simulations are performed for the consideration of antenna diversity characteristics.
