Microstrip antenna design using transmission line model in hexagonal shape with probe feed

Microstrip antennas generally prefer to printed antennas used for narrowband range at ultra-high frequencies and microwave communication. There are generally three basic methods of design microstrip antenna whose names are transmission line, cavity & full-wave model. This paper we use here the transmission line model for designing hexagonal shape having ground cut microstrip patch antennas. The key factors in the design of microstrip patch antennas having operating frequency, dielectric constant of substrate and height of dielectric substrate. We use microstrip patch antenna incorporated with left-handed metamaterial. The proposed antenna utilizes metamaterial structure in the substrate height of 1.6mm from the ground plane with loss tangent 0.002. The improvement in bandwidth of antenna, gain and reduction in return loss at 3.9 GHz resonant frequency. By use of this combination it has been seen that there is an improvement of return loss at -14db. These structures are simulated using IE3d Electromagnetic simulator of Zealand software incorporation with 4.4 dielectric constant of a substrate. This paper shows the hexagonal shape microstrip patch antenna using along with hexagonal cut at ground and loaded with metamaterial structure.
