Abstract: A radar signal device includes an antenna unit, a transmission circuit and a reception circuit. The antenna unit is used to concurrently transmit a transmission signal and receive a reception signal. The antenna unit includes a metal layer, a first feed structure and a second feed structure. An opening is formed on the metal layer. A first projection of the first feed structure on the metal layer at least partially overlaps with the opening. A second projection of the second feed structure on the metal layer at least partially overlaps with the opening. The antenna unit forms a first radiation pattern used to transmit the transmission signal and a second radiation pattern used to receive the reception signal. An angle between a co-polarized electric field direction of the first radiation pattern and a co-polarized electric field direction of the second radiation pattern is between 45 degrees and 135 degrees.

Abstract: A method of manufacturing an electronic package structure is disclosed. A solder mask layer is formed on an upper surface of a substrate. A recessed area is formed in the solder mask layer. An electronic component is mounted on the substrate. Pads are disposed on the upper surface of the substrate. The pads respectively correspond to the bumps on a first surface of the electronic component. The pads are electrically connected to the bumps. A heat treatment is performed to make the first surface close to the substrate and form a cavity in the recessed area. The cavity is between the first surface of the electronic component, the solder mask layer and the upper surface of the substrate.
