Title:
ANTENNA APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/140683
Kind Code:
A1
Abstract:
The present invention relates to an antenna apparatus. In particular, the antenna apparatus comprises: a radiating element module including a plurality of antenna sub-arrays electrically connected to the front of an RF filter and arranged to implement antenna beamforming by building a predetermined number of RF chains; and a phase shifter which shifts a phase value by changing the length ratio of a physical transmission line to the plurality of antenna sub-arrays to a predetermined ratio, wherein each RF chain of the radiating element module is implemented such that the antenna sub-array is connected to one output terminal of two output terminals branching off from an input terminal of each RF chain and an additional antenna sub-array corresponding to the antenna sub-array is further arranged to be connected to the other output terminal. Accordingly, a beam with a narrow beam width and a high antenna gain may be radiated, thus providing advantages in production cost and process.
