Item DESIGN OF VARIOUS MULTIBAND SLOT ANTENNAS(2022-02-28) MAHMOUD, WAFA MUSTAFA LAMIN; AYDIN, ElifIn these days, microstrip antennas cover a wide range of application in various 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 layer is called the patch and the bottom layer is called the ground. Between the patch and the ground there is the substrate layer which has a certain dielectric constant and thickness. The goal of this work is presenting a way of getting multi-band antennas for Wi-Fi devices and Wireless Communication System. These bands of frequency cover the standard IEEE 802.11b/g (2.4-2.485GHz) and IEEE 802.11a (5.15- 5.35GHz) for WLAN applications and 2.5 GHz (2.5-2.69GHZ), 3.5 GHz (3.3- 3.8GHz) and 5 GHz (5.25-5.85GHz) for Wi-MAX applications. We have used two different designs using program of software HFSS that has been used for simulation process. The multiband slot antennas have been simulated and manufactured by using two types of feeds. Firstly, the design of the antenna used the microstrip feed line and then we used the coplanar (CPW-Fed). Multi-band microstrip antennas were designed and simulated in terms of the return loss (S11) and the gain. These designs were fabricated and their return loss were measured and compared with the simulation results.
