Description
Technical Field

Background
In recent years, GPS has been widely used in many electronic communication products, and navigation using the GPS system is seen from driving in a car to walking or sports outdoors. At present, GPS navigation positioning system is used as basic standard in automobile or electronic communication products to be equipped with a satellite for transmission or provide downloading for use, so as to attract the desire for purchase. When the GPS navigation positioning system is used, the satellite is used for synchronously transmitting electric waves for positioning, and after the GPS navigation positioning system of a user receives the electric waves, the distance between the GPS navigation positioning system and the satellite can be calculated according to the time difference, and the GPS navigation positioning system stores the operation data of the satellites, so that the position of the user can be determined.
Currently, the satellite system for navigation positioning has two transmitting frequencies, and existing GPS satellites transmit a C/a code (with a length of 1023 bits) and 50 Bits Per Second (BPS) navigation data message from which the time is determined in the L1 channel signal at 1575.42 MHZ. The L1 channel also includes a P/Y military signal. Existing GPS satellites also transmit P/Y military signals over 1227.6MHZ channel L2.
Therefore, in order to receive the two transmission frequencies, the conventional GPS navigation positioning system integrates two circularly polarized antennas made of different materials (e.g., different dielectric constants) together, and uses a single signal feed together to enable the circularly polarized antenna to receive the 1575.42MHZ and 1227.6MHZ frequencies. Due to the use of two different dielectric constant materials, the dielectric constant of the materials is not easy to adjust, and the difficulty in manufacturing the circular polarized antenna is increased.
