Abstract :
An L-shaped probe fell microstrip antenna is investigated. The antenna is made of a rectangular patch supported by a thick foam dielectric layer. The patch is proximity fed via L-shaped probe. Simulation results confirm previously reported improvement in the bandwidth of 35%. The analyses are extended to examine the effect of supporting stacked patch above the original one. An impedance bandwidth of 46% has been achieved when the separation between the stacked parasitic patch and the original patch is 4.5 mm
