Problems solved by technology

For one-dimensional scanning waveguide slot antennas, as the gain of the array element increases, the working frequency band of the array element will become narrower, and it is difficult to meet the broadband requirements; for one-dimensional scanning microstrip line elements and oscillator line elements, it is necessary For the power combining network, as the gain of the array element increases, the network loss will increase, and accordingly, the heat consumption will also be greater

Abstract

The invention discloses a CTS array antenna system with a wide angle scanning function. A pair of quasi-planar wave discrete apparatuses are connected between a CTS antenna array surface and a slab waveguide feed source, so that discretization of the incident quasi-planar waves is realized, and a coaxial mode is converted, so that a conventional power division network is omitted; and by virtue ofan active assembly arranged between the pair of the quasi-planar wave discrete apparatuses, phase-control scanning of a wave beam is realized, thereby realizing relatively low feed loss and relativelylow heat consumption. Therefore, the CTS array antenna system with the wide angle scanning function disclosed in the invention has the characteristics of broadband, high gain and wide angle scanningand the advantages of low profile, low cost and low heat consumption.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a CTS array antenna system with a wide-angle scanning function. Background technique [0002] At present, the commonly used mechanically movable reflector antenna has a large envelope size; while the traditional one-dimensional scanning phased array antenna mostly uses waveguide slot line elements, microstrip line elements, and oscillator line elements. For one-dimensional scanning waveguide slot antennas, as the gain of the array element increases, the working frequency band of the array element will become narrower, and it is difficult to meet the broadband requirements; for one-dimensional scanning microstrip line elements and oscillator line elements, it is necessary In the power combining network, as the gain of the array element increases, the network loss will increase, and accordingly, the heat consumption will also be greater. Contents of the invention [0003] The t...
