Abstract

A dual-band enhanced-bandwidth microstrip antenna is presented with a frequency separation of f2/f1=1.33. In order to achieve the dual-frequency operation, a rectangular patch is loaded with a stub at one of its radiating edges. To improve bandwidth at each band, two parasitic patches are coupled to the driven element.
