Slot Antenna Miniaturization Using Copper Coated Circular Dielectric Material

Abstract

The contribution of this paper is to proposed a simple slot antenna miniaturization method using copper coated FR_4 dielectric material loading technique. The operating frequency for reference antenna and loaded antenna are 2.86GHz and 1.66GHz respectively. As a result, overall size of proposed antenna reduces by a ratio of 41.95%. A parametric study on various copper coated dielectric materials is presented to better understand the effect of the permittivity on slot antenna miniaturization. The antenna topologies are designed and analyzed using High Frequency Structure simulator (HFSS) tool. The prototype was fabricated and measured, and the measured results show good agreements with the simulated ones. This antenna can be very useful for various wireless communication systems.
