Document Type and Number:
WIPO Patent Application WO/2021/082704
Kind Code:
A1
Abstract:
Disclosed by the present application are an antenna and a door lock. The antenna comprises a substrate, the substrate is provided with a radiation piece and a metal piece, the metal piece is provided with an installation hole, and the radiation piece is located in the installation hole and is spaced apart from the metal piece. By means of adding a metal piece at the periphery of the radiation piece and isolating the metal piece from the radiation piece, the metal piece of the present invention may effectively isolate the electromagnetic effect that surrounds a metal environment, which is beneficial in preventing electromagnetic leakage in a metal environment region, so that energy may more fully radiate outwards toward the metal environment region. Thus, the gain of the antenna is increased such that the radiation piece can operate normally close to the metal environment, the anti-metal performance of the antenna is enhanced, and there is no need to provide clearance for the radiation piece.
