Design of multi band antenna for wireless communication

Abstract

In this paper, we proposed Inverted-F Antenna concept. We design a novel antenna that resonates at two different frequencies. Using only a single layer and single feed, the antenna operates at lower frequency of 1.4 GHz and at higher frequency of 3.2 GHz. The results obtained were acceptable in terms of return loss (RL), bandwidth, radiation pattern and gain. IFAs are suitable for wireless communication systems, and their structure is very simple. IFAs are low profile antennas, and it is printed type of antenna. In this research, the commercial software Computer Simulation Technology and High Frequency Structure Simulation (HFSS) were used to design the antenna and validate the results. The proposed antenna shows better performance than many existing systems.
