Design of Very Low Return Loss, Rectangular Microstrip Patch Antenna for Cellular and Mobile Communication
Cellular mobile communication is need of world. In this era life cannot imagine without cell phone. In this paper, it has been designed a two antenna for GSM communication at 1800MHz. First antenna is Rectangular Microstrip Patch Antenna (RMPA) and second one is Slit Slotted Rectangular Microstrip Patch Antenna (SSRMPA). Basic property of both the antenna like simulated design, returnloss, electric field distribution and radiation pattern is discussed. Finally, it is shown that return loss of antenna in slit-slot patch is decreased about 92.52% and antenna directivity is also increased a bit and total efficiency of slit-slot RMPA is increased about 12.48% slit-slot rectangular microstrip patch antenna also reduces the size of antenna which is always a basic need of cell phone antenna design system.
