Dual-frequency microstrip antenna array for the navigational system with the ability to suppress the active jammers
Planar dual-frequency microstrip antenna array with circular polarization was developed. Antenna array is optimized for the application in digital adaptive receiving system of satellite navigational signals GPS/GLONASS. The design of antenna array provides the manufacturing on dual layer microstrip subtrate of 10 compact ring radiators with circular polarization: 4+4 peripheral for each of the frequency bands L1 GLONASS (1593…1608) and L2 GLONASS (1237…1254 MHz) and 2 central radiators for the L1 GLONASS/GPS (1570-1608 MHz) та L2 GLONASS/GPS (1226 – 1254 MHz).
