Title:
QUASI-OMNIDIRECTIONAL ANTENNA AND SIGNAL TRANSMISSION AND RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/232689
Kind Code:
A1
Abstract:
A quasi-omnidirectional antenna and a signal transmission and reception device. The quasi-omnidirectional antenna comprises: a housing, the housing comprising a metal back housing facing a mounting area boundary and a front housing arranged opposite to the metal back housing; a front-facing antenna is disposed inside of the housing, and the front-facing antenna is used for radiation in a direction away from the metal back housing; also disposed inside of the housing are two side antennas, a first side antenna and a second side antenna of the two side antennas are arranged opposite to one another and on either side of the front-facing antenna; a metal ground of each side antenna of the two side antennas is connected to the metal back housing by means of a signal, such that the radiation area of each side antenna includes at least part of the area between the metal back housing and the mounting area boundary; the radiation area of each side antenna overlaps with the radiation area of the front-facing antenna. The quasi-omnidirectional antenna reduces the volume of an antenna apparatus while ensuring high gain for the antenna.
