Abstract


Microstrip antennas cover a wide range of application in different areas, such as internet services, mobile communication, and satellite navigation. Microstrip antenna consists of two metal layers and a substrate. In the two metal layers, the top one is called patch and the bottom layer is called ground. Between the patch and the ground, there is the substrate layer, which has a certain dielectric constant and thickness. The aim of this paper is to present a way of getting multi-band antennas for Wi-Fi devices. 2.5 GHz (2.5-2.69GHZ), 3.5 GHz (3.3-3.8GHz) and 5 GHz (5.25-5.85GHz) have been used for Wi-MAX applications. HFSS software has been used for simulation process. The multiband slot antennas have been simulated and manufactured. Multi-band microstrip antennas have been designed and simulated in terms of the return loss (S11) and the gain. These designs have been fabricated and their return loss has been measured and compared with the simulation results.
