GPS and IRIDIUM Antenna for Tracking

This paper describes the antenna design for application in tracking. We propose two structures with simulation, optimization and realization. These antennas are designed at two frequencies GPS (1575 MHz) and IRIDIUM (1616 MHz) with only one feeding. We opt for only one feeding in order to simplify the design of electronic parts and to reduce the cost of the beacon. We compare the design of two technologies in order to optimize the performances and the final cost of the beacon. The first design is a standard technology with printed antenna with soft substrate. The second used the thick film technology. These two technologies permit a local development by local companies.
