Abstract

An embodiment of the invention discloses an antenna, a manufacturing method of the antenna, a printed circuit board and a communication terminal. The antenna comprises a first radiating body, a second radiating body and feed points, wherein the first radiating body and the second radiating body are made of metal materials, and are separated with each other through a dielectric isolation portion, the first radiating body surrounds the second radiating body, and the feed points are in bridge joint at two ends of the dielectric isolation portion, and are connected with the first radiating body and the second radiating body. The antenna performance is achieved through electromagnetic coupling of the dielectric isolation portion between metal bodies, and therefore costs of communication equipment are reduced and space use rates of the printed circuit board are improved.

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 components used to transmit and receive wireless signals—antennas—are increasingly Miniaturization is urgently 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 effective use of t...
