Title:
DIRECTIONAL HIGH-GAIN ANTENNA AND REMOTE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/036596
Kind Code:
A1
Abstract:
The present disclosure provides a directional high-gain antenna and a remote control device, the directional high-gain antenna comprises: a substrate; a reflective type ground mechanism and an antenna mechanism arranged on the substrate; the reflective type ground mechanism is provided with a reflective notch which is provided with an opening facing the antenna mechanism and is used for reflecting electromagnetic waves of the antenna mechanism. The reflective notch is formed in the reflective type ground mechanism in an inward concave mode, the internal edge of the reflective notch is also used as a reflective oscillator, so that the directional high-gain antenna is enabled to present a current phase lag effect, the electromagnetic wave vector fields in the direction of the antenna mechanism towards the reflective notch are superposed and offset, and the electromagnetic wave vector fields in the direction of the reflective notch towards the antenna mechanism are superposed and enhanced, so that the electromagnetic wave radiation of the directional high-gain antenna has a directional gain effect.
