Miniaturization full-band high-gain PCB antenna

Abstract

The present invention discloses a miniaturization full-band high-gain PCB (Printed Circuit Board) antenna. The miniaturization full-band high-gain PCB antenna comprises an antenna radiator, a dielectric substrate and an antenna floor; the antenna radiator is located at the upper portion of the dielectric substrate, and the antenna floor is located at the lower portion of the dielectric substrate; the antenna radiator comprises an antenna main body, an antenna coupling body and a feed portion; the antenna main body and the antenna coupling body are connected with the feed portion; the antenna main body and the feed portion are provided with via holes; and the circuit of the antenna radiator is communicated with the circuit of the dielectric substrate through the via holes on the feed portion. One end of the antenna floor is provided with a clearance area, and the dielectric substrate is located in the clearance area. According to the mode, the miniaturization full-band high-gain PCB antenna reduces the size of the antenna, and is small in the occupied space to further save the space of an electronic device; and the small size of the antenna and the arrangement of a coupling circuit, the miniaturization full-band high-gain PCB antenna improves the antenna efficiency and can be installed on any one electronic device so as to satisfy the user requirement and improve the antenna practicality.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a miniaturized full-band high-gain PCB antenna. Background technique [0002] Communication products such as in-vehicle central controls, notebooks, televisions, and audio systems are all equipped with network functions, and PCB (Printed Circuit Board, printed circuit board) antennas are essential components. With the vigorous development of communication technology, communication products tend to be lighter and smaller, and the existing PCB antennas generally occupy a large space, which has certain limitations and is not conducive to popularization and application; and the efficiency of PCB antennas is affected by the surrounding environment Larger, in different environments in actual use, the effect of receiving and transmitting signals is not ideal. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a...
