Combined PCB antenna device

Abstract

This invention provides a combined PCB antenna device, including a substrate and a PCB antenna. A mounting module is provided between the PCB antenna and the substrate. A first mounting hole is provided on the substrate. The PCB antenna includes a PCB substrate, multiple first radiating arms, and multiple second radiating arms. A second mounting hole is provided on the PCB substrate. The first radiating arms are mounted in a swastika shape on the front side of the PCB substrate, and the second radiating arms are mounted in a swastika shape on the back side of the PCB substrate. The second mounting hole is located within the space enclosed by the first and second radiating arms. The mounting module includes a base post, a first mounting component at the upper end of the base post, and a second mounting component at the lower end of the base post. The first mounting component is inserted into the second mounting hole, and the second mounting component is inserted into the first mounting hole. The PCB antenna is arranged parallel to the substrate. This invention can reduce interference. The combination of the first and second radiating arms enclosing each other can effectively expand the matching bandwidth of the antenna. The mounting module makes the installation of the PCB antenna and the substrate simpler and faster.
