Abstract:
A multi-band antenna comprising two or more low frequency radiators dimensioned to operate in a low frequency band, and two or more high frequency radiators dimensioned to operate in a high frequency band. Each high frequency radiator is substantially coplanar with the low frequency radiators, and is formed in a spiral with the high and low frequency radiators interleaved. A hybrid feed network has two or more antenna ports, each antenna port being coupled with a low frequency radiator and a high frequency radiator. The antenna can be used for receiving GPS L1/L2 signals. The antenna is configured to send and/or receive circularly polarized radiation.
