They are integrated to collaborate with each other. It is important to improve the efficiency of the antenna to a accomplish requirement for the various applications using the same antenna [1]. In the U.K., emerging 4G high-performance (free service) unlicensed 5470–5725 MHz band (WiMAX) Worldwide Interoperability for Microwave Access mobile technology IEEE 802.16e has considered as a potential candidate for use in ITS [1]. ITS adopt traveling information in moving vehicles over highways. This information used to reduce environmental impact and to improve the transportation safety. Road safety an important issue because many people lose life in road accidents. Vehicle safety needs to go beyond the traditional safety technology in place which is mostly passive in nature such as seat belts and air bags .DSRC is a wireless communication technology which has been developed for the enhancement of safety of the transport system. It operates at (5.85-5.925 GHz) 5.9 GHz band[2].To support safe and efficient mobility of vehicles. The next step to further improve the transportation system of today is to make the vehicles and roadside infrastructure more intelligent by making them communicates with each other. This new ability will help find new solutions to current problems like traffic congestion, vehicle accident, monitoring of adherence to traffic rules and alerting the responsible authorities of any traffic rule violation or accident for immediate management [3].GPS is usually integrated to collaborate with the terrestrial ITS service. Furthermore, according to IEEE communication standards, time synchronization obtained by GPS is required for ITS services. Therefore, the automotive market requires compact, high- performance, and cheap solutions that accommodate GPS/ITS services with the smallest volume mounted on the roof of a vehicle. In [4], Dual-feed microstrip antenna for integrated GPS/ITS operation has presented. Due to poor impedance matching and the large size, the four-layer structure is difficult to employ. In this paper, present a coplanar integrated microstrip antenna solution for ITS services, which is about 40% less than the electrical size of the antenna. The design is being developed to satisfy not only ITS service but also 5.8-GHz DSRCS band. The geometry of the proposed ITS multifunctional antenna employs only a single dielectric layer, which is easy to fabricate and assemble in compliance with the space limitation requirements of the automotive market. 1.1 LITERATURE A) I.J.
