It is fixed in plastic shell, cellular communication antenna, navigation antenna and iridium satellite antenna are respectively mounted on a mounting board, navigation antenna,
Cellular communication antenna and iridium satellite antenna pass through 50 ohm coaxial lines and the first radio frequency connector, the second radio frequency connector, respectively
Three radio frequency connectors are connected.Double faced adhesive tape is pasted below antenna plastic shell, antenna can be made to be securely fixed in the top of car.Antenna
Overall dimension is 180 millimeters of 50 millimeters of x, 20 millimeters of x.The integral layout of three antennas is Chinese character pin-shaped, it is contemplated that iridium communication frequency
Both rate and cellular communication frequencies are close to (iridium satellite frequency：1616-1626.5MHz the high frequency 1710MHz with cellular communication antenna),
Make cellular communication antenna radiator and iridium satellite antenna remote during arrangement, to increase isolation.
Wherein cellular communication antenna is that planar inverted-F antenna (PIFA) plus parasitic oscillator are constituted, and antenna size is 180mm x
45mm x 15mm (the long wide x of x are high).
It is preferred that, cellular communication antenna can be realized with hard PCB, can also be realized with stamped metal.
Further, cellular communication antenna working frequency covering 824-960MHz and 1710-2170MHz.
Wherein navigation antenna can be gps antenna (frequency：1575.42MHz), BDS Beidou antennas (frequency：1561MHz)、
Glonass (GLONASS) antenna (frequency：1602MHz) or combinations thereof.
It is preferred that, navigation antenna is active antenna, i.e., comprising passive antenna and low-noise amplifier.
Further, the passive antenna in navigation antenna is ceramic medium antenna, and size is 25mm x 25mm x4mm (long
The wide x of x are high).The ceramic antenna of other dimensions can also be used.
Wherein iridium satellite antenna should receive signal, also want transmission signal, so being passive day without low-noise amplifier
Line.Operating frequency of antenna is 1616-1626.5MHz, right-handed circular polarization, gain 5dBic.
It is preferred that, iridium satellite antenna uses size for the ceramic medium antenna of 35mm x 35mm x 4mm (the long wide x of x are high),
It can be realized using bifilar helical antenna form.
By the technical solution of the utility model, it can be communicated when there is cellular communications network using cellular communications network,
And when not having cellular communications network, iridium communication net is switched to, so that real Global Link had both been realized, and communications cost
It is low.
