Title:
RADIATING STRUCTURE AND ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2020/228275
Kind Code:
A1
Abstract:
The present application provides a radiating structure and an array antenna, wherein the radiating structure comprises a radiating sheet which is provided with a radiating slot in the middle part, and the radiating slot comprises a horizontal slot and a longitudinal slot that are connected to each other and are cross-orthogonal to each other, and both the lengths of the horizontal slot and the longitudinal slot are less than that of the radiating sheet in an extending direction along the corresponding radiating slot. Radiating slots are additionally arranged in the radiating sheet such that the radiating structure may generate two kinds of radiation simultaneously when working in an antenna system, thereby achieving a superposition and enhancement effect of polarization vectors. Therefore, only one layer of radiating sheet is used to achieve the same radiation efficiency and radiation gain as that of the traditional antenna having a multiple-layer patch structure, thereby reducing the use of parts; and the structure is simple, and the antenna profile can be reduced, which is beneficial to the implementation of antenna miniaturization.
