A dual-band RHCP (right-hand circular polarization) microstrip patch antenna is presented for its implementation on a GNSS receiver covering the bands L2, E6 and L1. To improve the total efficiency at the band edges, a dual-band equalized is designed by implementing a dual-band filter matched to the complex impedance of the antenna. This filter is composed of two single-band filters, each of them designed to maximize the minimum efficiency in the correspondent band, connected together with input and output junctions. Moreover a microstrip prototype for the dual-band equalizer is designed and fullwave simulations show the equalized efficiency validating the theoretical results.
