Bandwidth enhancement of patch antenna with anisotropic substrateusing inset l-shaped feed and l slots on ground plane

الملخص EN

in this paper, an inset L-shaped feed rectangular patch antenna with dual L slots etched on the ground plane is proposed and analysed for increasing band width of microstrip patch antenna.

The results in terms of return loss and radiation pattern are given.The results show that dual wide bands are achieved and a better impedance matching for the upper and lower resonances are obtained.Simulation results for the effect of uniaxial substrate on the return loss and bandwidth of the rectangular patch antenna using inset L-shaped feed with dual rectangular slots on the ground plane are also presented.

Our results of return loss using Ansoft HFSS are compared with those available in the literature which shows a good agreement.
