Embodiment Construction

[0023] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0024] figure 1 A schematic diagram of the structure of a miniaturized broadband aperture waveguide circularly polarized antenna is given, as shown in figure 1 As shown, the miniaturized broadband aperture waveguide circularly polarized antenna consists of a coaxial waveguide converter, a rectangular waveguide cavity, a circular polarizer, and a mounting structure. The coaxial waveguide converter uses the L-shaped probe S1 to convert the coaxial signal into a linearly polarized signal and propagates in the rectangular waveguide cavity. Optionally, the rectangle is a semicircular rectangle with two ends. Different from the side-feed method of general coaxial waveguide converters, the L-shaped probe ...

Abstract

The present invention provides a broadband open-ended waveguide antenna, comprising a metal housing and a coaxial waveguide transducer, wherein the metal housing is in a shape of a column with two open ends, the inner cavity of the metal housing is successively a waveguide cavity and a transition cavity along the axial direction, the end, close to the transition cavity, of the metal housing is an installing structure; the coaxial waveguide transducer comprises an L-shaped probe and an RF connector, the L-shaped probe is fixedly connected with one end of the RF connector, the RF connector extends to the outer side of the transition cavity along the axis, so that the other end of the RF connector can be detachably connected with an RF channel. Through adoption of the above technical scheme, the broadband open-ended waveguide antenna which is easy to install and detach is achieved.

Description

technical field [0001] The invention relates to the field of microwave engineering, in particular to a broadband aperture waveguide antenna. Background technique [0002] At present, the main implementation forms of K or Ka-band antennas include waveguide slots, microstrip Yagis, and microstrip patches. Among them, the circular polarization scheme of waveguide slots and microstrip Yagi is more complicated, and it is not easy to realize the array, so the realization form of microstrip patch is mostly used. [0003] Microstrip patch antennas have been widely used due to many advantages such as small size, light weight, thin profile, easy to conform to the carrier, and simple manufacturing process. Rectangular patch cut corner is a circularly polarized microstrip antenna with simple structure and easy implementation. It is often used as a unit of circularly polarized antenna array. It adopts single feed to realize circular polarization, which saves space and facilitates array ...
