【 摘 要 】

Advances in communication technology using radio wave continue to increase including in Global Positioning System (GPS). This triggered the emergence of various kinds of research and development in the field of radio wave communication. One of the most widely developed devices today is the antenna. Various innovations and antenna technologies are emerging. In this paper, we will design a high gain microstrip patch antenna with circular polarization characteristics that can be used for GPS applications operating in the L1 1.575 GHz frequency region. The microstrip antenna design consists of a patch radiator with a dual-feed line in order to produce a circular polarization. The design process of this antenna starts with the determination of the antenna specification, calculate the antenna dimension, designs and simulation the antenna using CST Studio Suite software, realizes the antenna, and analyzes the simulation results and the measurement of the antenna. The simulation results show gain of our propose antenna design simulation on the L1 frequency, that is: gain is 6.254 dB, the bandwidth of antenna is 290 Mhz from 1.366 GHz to 1.655 GHz for return loss less than -10 dB with return loss -20.77 dB and axial ratio is 2.38.
