Abstract
This paper introduces the novel Ultra-Wide Band (UWB) antennas for UWB applications. We used two different structures, the first is fed by micro-strip line and the second is a compact coplanar waveguide fed planar slot antenna. These designs are a small on planar antenna. The substrate used is FR4 that have the characteristics following: Permittivity εr = 4.4 Impulse Radio Ultra Wide Band systems (IR-UWB). The frequency central is 5.6 GHz and shows good characteristics for IR-UWB. The radiation pattern and gain are simulated and we compared between the different results we have obtained.
Highlights
In the Internet development, wireless communications with mobile vehicles becomes a new challenge because most computers and almost all “mobile” devices have means for connection to one or more types of wireless networks such as WiFi, Bluetooth or infrared (Sabattier, 2008)
We offer two new Ultra Wide-Band antennas for Ultra-Wide Band (UWB) applications and for communicate with mobile vehicles, we are interested exclusively on the base station and as an application, we proposed the implementation of these antennas near propose to design high gain antennas to maximize their range and minimize their number (Ahmed and Sebak, 2008)
First Configuration: The UWB Antenna with two Slots In Fig. 1, we present a new UWB patch antenna which consists of a rectangular patch with two slots, two steps and a partial ground plane (Vuong et al, 2007)
Summary
In the Internet development, wireless communications with mobile vehicles becomes a new challenge because most computers and almost all “mobile” devices (such as mobile phones) have means for connection to one or more types of wireless networks such as WiFi, Bluetooth or infrared (Sabattier, 2008). This antenna has been printed on a FR4 epoxy substrate with thickness h = 1.6 mm and permittivity (εr = 4.4, tan δ = 0.0009).
