A Comparative Study of Two Different Type of Metamaterial Unit Cells for Miniaturization and Multiband of Microstrip Patch Antenna at 2.4 GHz Frequency

Abstract

Abstract In this paper we design a multiband microstrip patch antenna (MPA) metamaterial (MM). We used two different types of MM unit cells and loaded these unit cells on the antenna, respectively. Thus, it can be decided which metamaterial is more appropriate for multiband and size reduction. One MM structure is new proposed geometry. It is in the shape of a Hindu mythological symbol ‘Swastiks’ and another MM unit cell is conventional split ring resonator. Before designing the MM loaded antenna, we analyze the characteristics of both kind of MM unit cells. We use the HFSS software for the simulation purpose.
