Embodiment 1

[0027] In this embodiment, the center frequency of the end-fire array antenna unit is 3 GHz, and the unit size is 0.4 times the wavelength of the center frequency. Such as figure 1 , figure 2 Shown is the 8×8 unit monopole end-firing array antenna of the present invention, which includes a metal reflector 1 , a monopole end-firing array antenna unit 2 , a slot structure unit 3 , and a radio frequency connector 4 . The number of monopole end-radiation array antenna units 2 is 64, the number of slot structure units 3 is 144, and the number of radio frequency connectors 4 is 64. In this embodiment, the inner conductor of the radio frequency connector 4 and the monopole are integrally processed and manufactured, and the monopole end-radiation array antenna unit 2 is fed. The installation of the antenna unit 2 at the pole end is fixed.

[0028] Such as image 3 As shown, in this embodiment, the unit spacing of the monopole end-fire array antenna unit 2 is Wm, the height of the...

Abstract

The invention discloses an omnidirectional scanning monopole end-fire array antenna of a horizontal beam. The omnidirectional scanning monopole end-fire array antenna comprises a metal reflecting plate, end-fire array antenna units, slot structure units and a radio frequency connector, wherein the end-fire array antenna units are periodically arranged on the metal reflecting plate, the slot structure units are periodically arranged on the metal reflecting plate, and the slot structure units are arranged in the middle of the adjacent end-fire array antenna units. The monopole end-fire array antenna provided by the invention has beams which are completely radiated in the horizontal end direction, solves the problem that beams of a traditional end-fire array antenna are warped upwards, and issimple in structure, easy to process and manufacture and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of end-fire array antennas, and in particular relates to an omnidirectional scanning monopole end-fire array antenna with a horizontal beam. Background technique [0002] The electrical scanning characteristics of phased array antennas have the advantages of fast and agile and have been widely used in the fields of radar and communication. At present, the development of side-firing phased array technology has been relatively mature, and it is also widely used in the fields of radar and communication. For side-firing arrays, a larger array aperture is required to achieve high gain, which has certain limitations in some small platforms such as airborne and high-gain application scenarios. End-fire array is one of the forms of phased array antennas, and its radiation direction is along the axis of the array arrangement, which is the end-fire direction. Therefore, in the application of end-fire arrays, its radi...
