Design of dual band micro strip antenna for 2.4 Ghz and 3.6 Ghz

Abstract

As technology is growing, it has created a need for the antennas to transmit/ receive at faster rate, with more than one frequency at a time. This is possible with use of dual band antenna. In the given paper, the design of microstrip rectangular patch antenna for dual band application that uses two frequencies, 3.6GHz and 2.4GHz, is presented. The antenna consists of two rectangular slots, positioned on the rectangular patch which is mounted on the ground substrate made of FR4 epoxy. The standard antenna formulae are used to find the dimensions of the patch and positioning of the rectangular slots, and simulation-based optimization techniques in Ansys HFSS (High-Frequency Structural Simulator-a computer software dealing with 3D electromagnetic models). The position of slots determines the operating frequencies of the antenna. The dual band antennas are commercially used in routers, where there is a need for faster data rate.
