Abstract

The invention relates to a linear array vehicle-mounted antenna and device. The linear array vehicle-mounted antenna comprises a power division network, at least two feed networks, a nonmetal supporting assembly and at least two radiation array elements, wherein one radiation array element corresponds to one feed network; the power division network is in feed connection with the at least two radiation array elements through the at least two feed networks; every two adjacent radiation array elements are connected through a supporting assembly. Each radiation array element comprises a first radiation oscillator and a second radiation oscillator which are oppositely arranged and are mutually symmetrical; each of the first radiation oscillator and the second radiation oscillator comprises a first circular truncated cone radiator, a columnar radiator and a second circular truncated cone radiator, one end of the first circular truncated cone radiator is connected with one end of the columnar radiator, and the other end of the columnar radiator is connected with one end of the second circular truncated cone radiator; and the second circular truncated cone radiators of the first radiation oscillator and the second radiation oscillator are oppositely arranged. The linear array vehicle-mounted antenna can meet the communication requirements of wide band, high gain, vertical polarization and horizontal omnidirectional.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a linear array vehicle-mounted antenna and equipment. Background technique [0002] When realizing vehicle-to-vehicle, vehicle-to-fixed station communication, it is usually achieved by means of a whip antenna. [0003] With the development of military radio stations in our country, the working frequency band of radio stations is required to be wider and wider. Since the whip antenna is usually used in a narrow-band working state, multiple whip antennas will be arranged on the vehicle in order to meet the requirements of the wide working frequency band of the radio station. [0004] However, the communication quality is degraded due to the short distance between multiple whip antennas and the strong coupling. Contents of the invention [0005] Based on this, it is necessary to address the above technical problems and provide a linear array vehicle-mounted antenna an...
