The Design of Dual Band Circularly Polarized Patch Antenna for Civilian GPS Applications

Abstract:

Antenna is all important part of GPS receivers，there is a great need for the design and production of new antennas which are fully compatible with modernized signals. Because of their advantages such as low cost, compact size, low profile，ability to support dual-frequency and circular polarization operation, microstrip patch antennas have become widely used in GPS antenna designs. A circular polarization patch antennas are proposed in the paper. The antenna designed to operate at L1(1575.42MHz) and L5(1176.45MHz)frequency bands. Initially, a comer-truncated patch antenna for GPS L1 operation was designed to validate simulation in Ansoft High Frequency Structure Simulator(HFSS), the results obtained for this antenna were used to design the two proposed antennas,and designed antennas are presented．
