The analysis of dual band double U-slot cut rectangular microstrip antenna is presented. The reported double U-slot cut rectangular microstrip antenna yields dual and wide band operation in 2100 and 5400 MHz frequency bands. To analyze the dual band response at above frequencies, the resonance curve plots and surface current distributions for equivalent rectangular patch and single U-slot and further double U-slot cut rectangular microstrip antennas were studied. The first U-slot primarily optimizes the position of TM01 and TM20 modes of the patch to realize dual and wide frequency response in 2100 MHz frequency range.
