A thin phased array antenna structure

Abstract

The invention relates to the technical field of satellite communication radar, and provides a thin phased array antenna structure, which includes a radome body, a patch antenna, a fur button integrated board, a thin radio frequency module and a control power supply board connected in sequence; the patch antenna includes an antenna Carrier board, one side of the antenna carrier board is provided with a number of antenna units evenly spaced in a rectangular array, and the other side of the antenna carrier board is provided with a radio frequency signal transmission pad corresponding to each antenna unit; the radio frequency signal transmission pad of the antenna unit passes through The fur button integrated board communicates with the thin radio frequency module; the lower cavity structure of the thin radio frequency module fits the fur button integrated board and the lower cavity structure is provided with a radio frequency signal link, a self-calibration signal link and a radio frequency power supply board; the control power supply board It is arranged in the upper cavity of the thin radio frequency module and electrically connected with the radio frequency power supply board. The invention processes the overall structure according to flattening, which not only meets the requirements of small size and light weight, but also improves the operating reliability of the antenna.

Description

technical field [0001] The invention relates to the technical field of satellite communication radar, and relates to a two-dimensional electronically scanned X-band active phased array antenna, which is mainly used to realize the communication function between satellites and the ground, and specifically relates to a thin phased array antenna structure. Background technique [0002] The low-orbit small satellites often use traditional servo-driven reflector antennas for ground-to-ground communication. Since the antenna needs to be driven by a servo mechanism to adjust the direction, it requires a large space, and due to the limitation of the rotation mechanism, the steering is relatively difficult. Slow, the reliability of the transmission mechanism is low. [0003] Upgrading the traditional reflector antenna to an active phased array antenna will greatly reduce the volume space required by the antenna, and the phased array antenna has the advantages of a large pointing range...
