Embodiment Construction
[0015] Technical solution of the present invention is:
[0016] A CAPS / Beidou dual-mode receiver includes: an antenna module, a radio frequency channel module, a Beidou information processing unit, and a microprocessor unit.
[0017] The antenna module includes a CAPS / Beidou dual-mode antenna (is such an antenna a known prior art? If not, its structure needs to be described.), power splitter, CAPS filter, amplifying unit, Beidou filter, amplify unit. Since the CAPS receiver must simultaneously receive signals from multiple satellites in different directions, it should be an omnidirectional antenna designed with circular polarization. The CAPS / Beidou dual-mode antenna adopts a single-point backfeed mode. The CAPS microstrip patch antenna and the Beidou microstrip patch antenna pass through a metal probe that passes through the dielectric board and the frequency point on the dielectric backplane is at a narrow band low of 4GHz. Noise amplifier and narrowband low noise amplifie...
