Abstract

The invention relates to phased-array antenna equipment, a wide-angle impedance matching device of the phased-array antenna equipment and a phased-array antenna system. The phased-array antenna equipment comprises an antenna device array and the wide-angle impedance matching device arranged above the antenna device array. The wide-angle impedance matching device comprises a first substrate, a plurality of horizontal conductive geometrical structures and a plurality of vertical conductive geometrical structures. The horizontal conductive geometrical structures are horizontally arranged on one surface of the first substrate, the vertical conductive geometrical structures are arranged above or below the horizontal conductive geometrical structures and are arrayed to be perpendicular to the first substrate roughly. The phased-array antenna equipment and the wide-angle impedance matching device of the phased-array antenna equipment have the following advantages that the influence of scanning blind points on a required frequency band is reduced, wide-band and wide-angle phased array scanning impedance matching is achieved, hence, the wide-angle scanning gain is improved, the scanning coverage is expanded, and the antenna scanning performance is improved.

Description

technical field

[0001] The invention relates to a phased array antenna device, a wide-angle impedance matching device for the phased array antenna device, and a phased array antenna system. Background technique

[0002] Due to its unique features such as fast beam scanning and beam forming, phased array radar has become the main trend of radar development. Antenna design for phased array radars is also an important area. The development of modern radar requires that the working bandwidth of the antenna is wide enough, the scanning range is large, and the standing wave should be small. Airborne phased array radars generally use Vivaldi type broadband antennas and use triangular arrays. The antenna has several types of scanning blind spots. As the scanning angle of the antenna increases, the blind spots move inward, thereby affecting the bandwidth and scanning performance.

[0003] In order to solve the above problems, that is, in order to reduce the impact of scanning blin...
