Abstract: The present invention provides a device without blocking wireless signals based on impedance matching. The device is constructed by periodically stacking two building materials with different dielectric constants in the same direction. The device without blocking wireless signals based on impedance matching can be designed as a wall body, and can improve wave transmission of microwaves to ensure that wireless signals won't be blocked at any incident angle, thereby achieving the unblocked transmission of wireless signals. Furthermore, compared with metal hole arrays, the component materials of the devices can include polypropylene and concrete, that expands the applications from micro circuit electronic devices to macro walls, and greatly reduces the manufacturing and maintenance cost.
