Abstract

This project proposed to study the antenna in GPS (Global Positioning System), designing the antenna and fabricate it. The GPS is a system that is able to determine the location of object and human on the earth. GPS has become a vital global utility, indispensable for modem navigation on land, sea, and air around the world, as well as an important tool for map-making, and land surveying. GPS also provides an extremely precise time reference, required for telecommunications and some scientific research, including the study of earthquakes. The frequency that use for GPS is 1575.42 Mhz. The main objective ofthis project is to design and fabricate a cheap GPS antenna. The best way to fabricate a cheap antenna is by using the microstrip antenna technology. The microstrip antennas are manufactured using printed-circuit technology, so that mass production can be achieved at a low cost. Microstrip antennas have several advantages, including that they are lightweight and small-volume and they can be conformal to the host-surface. Microstrip technology which are used for defense and commercial application, are replacing many conversional antennas. However, the types of applications of micro strip antennas are restricted by antennas inherently narrow bandwidth.
