Title:
アンテナおよび通信デバイス
Document Type and Number:
Japanese Patent JP6702528
Kind Code:
B2
Abstract:
This application discloses an antenna and a communications device. The antenna includes a feeding element and at least one non-feeding element. A vertical distance between each non-feeding element and the feeding element falls within a specified threshold, each non-feeding element includes a first conductor that is grounded, a regulator circuit, and a control switch that is disposed on the first conductor and that is configured to control the regulator circuit, where the regulator circuit is configured to regulate a current path length of the non-feeding element. The non-feeding element forms a reflector when the regulator circuit is enabled, or the non-feeding element forms a director when the regulator circuit is disabled. A design in which the reflector and the director are compatible is used, so that a combination of one feeding element, M directors and N reflectors is implemented for the antenna, to achieve a high directive gain and interference suppression capability, where M + N >= 1, and M + N = quantity of non-feeding elements. In addition, when the reflector and the director are switched, antenna beam switching can be rapidly completed, featuring easy implementation and a small size.
