Title:
BIPOLAR ANTENNA ASSEMBLY AND ONE-HANDED CONTROL TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/134249
Kind Code:
A1
Abstract:
A bipolar 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) opposite to each other; the first radiator (20) is provide on the first surface (11); the first radiator (20) is used for receiving or emitting an electromagnetic wave in a first polarization direction, and comprises a first high-frequency radiation branch (21) and a first low-frequency radiation branch (22); the second radiator (30) is provided on the second surface (12); the second radiator (30) is used for receiving or emitting an electromagnetic wave in a second polarization direction, and comprises a second high-frequency radiation branch (31) and a second low-frequency radiation branch (32); the first polarization direction is different from the second polarization direction; and a projection of the second high-frequency radiation branch (31) on the first surface (11) is adjacent to the projection of the first low-frequency radiation branch (22), such that the problem of polarization mismatch between a controlled end and a control terminal when the attitude of the controlled end changes greatly is solved. The present application also relates to a one-handed control terminal (1000).
