US 2019/0058254 A1 · Antenna and communications device

Abstract

An 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 disposed on the first conductor and 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 such 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.

Dependent claims

An antenna, comprising:

a feeding element;
and
at least one non-feeding element coupled to the feeding element, a distance between each of the at least one non-feeding element and the feeding element falling within a specified threshold, and each of the at least one non-feeding element comprising:
a first conductor that is grounded;
a control switch coupled to the first conductor;
and
a regulator circuit coupled to the first conductor and the control switch and configured to regulate a current path length of the at least one non-feeding element, and either:
a current being configured to flow through the first conductor and the regulator circuit when the control switch is turned off, the current path length of the at least one non-feeding element being greater than a resonance length of the feeding element;
or
the current being configured to flow through the first conductor and the control switch when the control switch is turned on, the current path length of the at least one non-feeding element being less than the resonance length of the feeding element.
