Wideband microstrip antenna for land based vehicles

Abstract

The objective of this project is to design, construct and fabricate microstrip antennas suitable for land based vehicles application centered at 2.4GHz. The antenna must operate within the unlicensed 2.4GHz band. This band is currently being used for the IEEE 802.11b and g standard and other industrial, medical and scientific applications. The antenna is proposed to be used as a transmitting as well as receiving antenna in wireless LANs and the mentioned applications. A rectangular microstrip prototype antenna was produced, with the bandwidth of 7.8 percent. The antenna covers the 2.4GHz band for wireless LAN with the bandwidth from 2.33GHz to 2.52 GHz. The antenna was fabricated on woven fiberglass substrate, that had a relative dielectric constant, εr = 4.88, a loss tangent tan δ = 0.001 and thickness, h of 1.57 mm.
