Abstract

Disclosed are an antenna and a manufacturing method thereof, a printed circuit board, and a communications terminal. The antenna comprises: a first radiator and a second radiator that are made of metal, the first radiator and the second radiator being isolated from each other by a dielectric isolation member, and the first radiator surrounding the second radiator; and feed points connected across two ends of the dielectric isolation member, connecting the first radiator and the second radiator. The antenna performance is achieved through the electromagnetic coupling of the dielectric isolation member between metal bodies, thereby reducing the costs of communications devices and improving the spatial utilization of the printed circuit board.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to an antenna and a manufacturing method thereof, a printed circuit board and a communication terminal. Background technique [0002] With the continuous development and popularization of mobile wireless communications, the miniaturization of terminal equipment and the complexity of the printed circuit board (PCB) environment of products, the antenna, the component used to transmit and receive wireless signals, is becoming more and more urgent. Miniaturization is required. However, from the perspective of the existing antenna forms, due to the constraints of the product layout environment, the headroom space required for the realization of antenna bandwidth, efficiency, and out-of-roundness is becoming more and more difficult to meet, increasing product performance indicators to meet user requirements difficulty. Therefore, it is particularly urgent to make effect...
