Multi Layer Aperture Coupled Micro Strip Antenna with Variation in Dielectric Constants
Journal Title: International Journal of Science and Research (IJSR) - Year 2013, Vol 2, Issue 1
Abstract
Micro strip antennas are used for low profile antenna applications. These antennas are always attractive for researchers due to their low cost, light weight, small size and ease in fabrication. Micro strip antennas are the antenna with High Gain and wide bandwidth. This paper presents aperture coupled micro strip antennas with variation in substrate material’s dielectric constants using multilayer configuration. Three designs of micro strip antenna are experimented and simulated through HFSS software, and compared to each other. The three designs are first is ‘conventional rectangular patch antenna’ (design 1), second is ‘sandwiched- multilayer rectangular patch’ (design 2), & third is ‘Non-sandwiched multilayer rectangular patch’ (design 3). All three designs, it was observed that multilayer structures are complex in fabrication & higher in cost, but they can deliver better performance as compare to single layer micro strip antenna, as per requirements
