Abstract :
The aim of this paper is to investigate microstrip multilayer antenna using computer simulation technology (CST-2010) simulation. In this way, improvement bandwidth of the patch antenna is increased by using multiple layer dielectric substrates. It is known that bandwidth of microstrip antenna is small and varies directly with the size of the patch, increasing size of patch to improve bandwidth makes it large. Thus to overcome the bandwidth limitation without increasing antenna size, a patch on multiple layer scheme has been designed to reduce the effective dielectric constant. This ensures that bandwidth increases greatly while size is not change. Performance parameters like bandwidth and reflection loss have been evaluated and compared with that obtained from single layer substrates. Results suggest considerable improvement in bandwidth using the proposed patch antenna design on multi layered substrate. The designed patch has a size of 8*8*2 mm3 and gives a bandwidth and gain of 920 MHz and gain 2.8 dB at 5.491GHz.
