Embodiment Construction

[0041] see Figure 1~3 , taking Embodiment 1 of the vehicle-mounted omnidirectional dipole antenna of the present invention as an example, the present invention provides a vehicle-mounted omnidirectional dipole antenna, which includes a sleeve 6 coaxially arranged and connected sequentially from bottom to top, a first A conductor segment 1, a first helical body 2, a second conductor segment 3, a second helical body 4, and a third conductor segment 5 loaded and connected to the top of the second conductor segment. The sleeve includes a first cylindrical section 61, a conical section 62, and a second cylindrical section 63 connected from bottom to top. Consistent, the diameter of the second cylindrical section is consistent with the diameter of the upper end of the conical section, and a coaxial cable 7 passing from bottom to top is provided on the central axis of the sleeve, and the outer conductor of the coaxial cable is connected to the top end of the sleeve. The inner condu...

Abstract

The invention discloses a vehicle-mounted all-around dipole antenna. The vehicle-mounted all-around dipole antenna comprises a sleeve, a first conductor section, a first spiral body, a second conductor section, a second spiral body and a third conductor section which are coaxially arranged from the bottom up and are in loaded connection in sequence, wherein the sleeve comprises a first cylindrical section, a conical section and a second cylindrical section which are connected from the bottom up; the conductor sections and spiral sections are connected through L-shaped bent conductor sections; the third conductor section is nested or not nested in a second spiral section; the diameter of the first cylindrical section is greater than that of the second cylindrical section; the diameter of the first cylindrical section is consistent with that of the lower end of the conical section; the diameter of the second cylindrical section is consistent with that of the upper end of the conical section; a coaxial cable which passes through from the bottom up is arranged in the central axis of the sleeve; an outer conductor of the coaxial cable is connected with the top end of the sleeve; and an inner conductor of the coaxial cable extends upwardly to be connected with the bottom of the first conductor section. By adoption of the vehicle-mounted all-around dipole antenna, high matching, high gain and increased bandwidth of the antenna are realized; and in addition, the vehicle-mounted all-around dipole antenna is small in design dimensions, high in structural strength, economical and durable.

Description

[0001] 【Technical field】 [0002] The invention relates to mobile communication base station / terminal antenna equipment and technology, in particular to an omnidirectional high-gain dipole antenna suitable for vehicles. [0003] 【Background technique】 [0004] At present, mankind has entered the information age in an all-round way, and obtaining information has become an indispensable and important part of people's daily life.
