Abstract

A dual polarized antenna assembly (102), comprising a substrate (10), a first radiator (20) and a second radiator (30); the substrate (10) comprises a first surface (11) and a second surface (12) which are opposite to each other; the first radiator (20) is arranged on the first surface (11), the first radiator (20) is used for receiving or transmitting electromagnetic waves in a first polarization direction, and the first radiator (20) comprises a first high-frequency radiation branch knot (21) and a first low-frequency radiation branch knot (22); the second radiator (30) is arranged on the second surface (12), the second radiator (30) is used for receiving or transmitting electromagnetic waves in a second polarization direction, and the second radiator (30) comprises a second high-frequency radiation branch knot (31) and a second low-frequency radiation branch knot (32); the first polarization direction is different from the second polarization direction, and the projection of the second high-frequency radiation branch knot (31) on the first surface (11) is adjacent to the first low-frequency radiation branch knot (22). Therefore, the problem of polarization mismatch between the controlled terminal and the control terminal when the attitude change of the controlled terminal is large is solved. The invention also relates to a one-hand-held control terminal (1000).

Description

technical field [0001] The present application relates to the field of antenna technology, and in particular, to a dual-polarized antenna assembly and a single-hand-held control terminal. Background technique [0002] The antenna on the UAV is usually set in a fixed position such as the arm, tripod, etc. The antenna is fixed relative to the fuselage of the UAV, and the polarization direction of the electromagnetic wave emitted by the antenna on the UAV is related to the attitude of the UAV. If the UAV has a large attitude change during flight, it may cause polarization mismatch between the UAV and the remote control antenna. For example, if the polarization direction of the electromagnetic wave emitted by the antenna of the drone is the horizontal direction, and the polarization direction of the antenna on the remote control is the vertical direction, the remote control will not be able to receive the electromagnetic wave emitted by the antenna of the drone, resulting in Co...
