Embodiment Construction

[0022] combined with figure 1 , 2 , 3, 4, 5 describe an embodiment of the present invention.

[0023] A vehicle-mounted ultrashort-wave broadband antenna has a 1.8m short radiator 1, a 3m long radiator 2 and a base 3, and the lower end of the short radiator 1 or the long radiator 2 is mounted on the upper end of the base 3 through screw connections. The short radiator 1 is composed of a radiator core 5, a matching device 6, a joint 7 and a glass steel pipe 8; It is fixed at the lower end of the glass steel pipe 8 , and the upper end of the matcher 6 is connected to the lower end of the radiator core 5 , and the lower end of the matcher 6 is connected to the upper signal interface 24 of the base 3 . The top of the short radiator 1 is covered with an antenna cap 9 . The long radiator 2 is composed of an upper radiator 10 and a lower radiator 11 screwed together.

[0024] The base is mainly composed of a base insulator 22 , a lower signal interface 23 , an upper signal interf...

Abstract

The invention relates to a vehicle-mounted ultrashort wave wide antenna, which consists of a short radiator, a long radiator and a pedestal, wherein the bottom end of the short radiator or the long radiator is installed at the upper end of the pedestal; the short radiator consists of a radiator core, a matcher, a coupling and a glass reinforced plastic pipe; the radiator core is inserted into the upper end of the glass reinforced plastic pipe; the matcher is fixed at the middle part of the glass reinforced plastic pipe; the coupling is fixed at the lower end of the glass reinforced plastic pipe; the upper end of the matcher is connected with the lower end of the radiator core; and the lower end of the matcher is connected with the upper signal port of the pedestal. A broadband impedance matching technology is employed, the problem of antenna height is well solved and good broadband impedance matching is realized, so antenna radiation efficiency is effectively improved, and antenna gain is increased. In the invention, two radiators use a pedestal, the short radiator or the long radiator can be selected during the tactical operation in a wide zone, the short radiator can be selected during short-distance networking, or passing through bridges and tunnels and quick movement, so the antenna is convenient for the army to use to the full extent.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a vehicle-mounted ultrashort-wave broadband antenna, which is suitable for a vehicle-mounted ultrashort-wave frequency-hopping radio station. Background technique [0002] The existing ultrashort wave vehicle antenna is generally a 3m center-fed antenna, and its performance index can meet the requirements of the vehicle-mounted ultrashort wave radio station. However, because the antenna is too high, it affects the smooth passage of communication vehicles through bridges and tunnels, avoiding satellites entering bridges and tunnels, and communication during fast movement. The effect is not good; in addition, with the increasing complexity of the electromagnetic environment and the higher and higher requirements for tactical communication, new requirements are put forward for ultrashort wave antennas, especially the tactical posture and communication effects of the ante...
