The invention discloses an anti-interference antenna with a direct connection function; the antenna comprises a radio-frequency unit formed by a BD four-element array, a four-way beidou low noise amplifier and path, a one-way beidou low noise amplifier, a local oscillator, an upper-conversion, a combiner, a GPS oscillator, a GPS low noise amplifier, and a radio-frequency amplifier; the antenna also comprises an anti-interference unit, a LDO1 power supply unit, a LDO2 power supply unit, a power supply and BD / GPS detection unit, and a single chip containing an antenna work procedure. When the anti-interference function of the antenna fails, the antenna can enter a direct connection work state so as to ensure normal work of the antenna; the antenna can realize controlled direct connection function: the antenna can have the direct connection function when receiving an outer direct connection order; the antenna has the fault direct connection function: the antenna can have the direct connection ability when the anti-interference unit of the anti-interference antenna fails.
Description
technical field [0001] The invention relates to an anti-jamming antenna, in particular to an anti-jamming antenna with a through function. Background technique [0002] The existing anti-jamming antenna only has a separate anti-jamming function (excluding LDO2 power supply unit, LDO1 power supply unit and single-chip microcomputer), and when the anti-jamming unit fails, the antenna cannot work normally. Contents of the invention [0003] In view of the defects and deficiencies in the prior art, the present invention provides an anti-jamming antenna with a through function. This design adds LDO2 power supply unit D, LDO1 power supply unit H and single-chip microcomputer J on the basis of the original anti-jamming antenna to realize the controlled direct function of the anti-jamming antenna. [0004] The technical solution adopted by the present invention to achieve the above purpose is: an anti-jamming antenna with a direct function, characterized in that it includes four ...
