AI Technical Summary
How to reduce the size of satellite positioning antennas without affecting their performance to meet end-users' miniaturization needs and achieve dual-band right-hand circular polarization performance.
A dual-band satellite positioning antenna is formed by using two dielectric layers with different dielectric constants and combining the coupling of the main radiator and parasitic branches. The feed point and ground layer are connected through the holes in the first and second dielectric layers to achieve right-handed circular polarization performance.
While reducing the size of the satellite positioning antenna, the circular polarization performance and signal reception effect of the dual-band were maintained or improved, and the manufacturing cost was reduced.
