Patent number: 12095179Abstract: An electronic device includes a metal back cover and an antenna module. The metal back cover includes a slit. The antenna module is separated from the metal back cover and disposed far away from the slit. The antenna module includes an antenna radiator, a first ground radiator, and a connection radiator. The antenna radiator includes a first section, a second section, and a third section that are sequentially connected and form bends, and the first section has a feeding end. A first slot is formed between the first ground radiator, the first section, the second section, and a part of the third section. A width and length of the first slot are associated with a center frequency and impedance matching of a high frequency band.Type: GrantFiled: August 29, 2022Date of Patent: September 17, 2024Assignee: PEGATRON CORPORATIONInventors: Chien-Yi Wu, Chao-Hsu Wu, Hau Yuen Tan, Cheng-Hsiung Wu, Chen-Kuang Wang, Tse-Hsuan Wang, Sheng-Chin Hsu, Shih-Keng Huang, Chia-Hung Chen

Patent number: 12080943Abstract: An antenna module disposed on a substrate having a first and a second surface opposite to each other includes a microstrip line, a first radiator, a ground radiator and a ground plane. The microstrip line, the first radiator and the ground radiator are disposed on the first surface. The microstrip line includes a first and a second end opposite to each other. The first end includes a first feeding end. The first radiator is connected to the second end of the microstrip line. The ground radiator surrounds the microstrip line and the first radiator and has a first opening and two opposite grounding ends. The first end of the microstrip line is located in the first opening. A gap is formed between each grounding end and the first feeding end. The ground plane is disposed on the second surface. The ground radiator is connected to the ground plane.Type: GrantFiled: February 22, 2022Date of Patent: September 3, 2024Assignee: PEGATRON CORPORATIONInventors: Chien-Yi Wu, Tse-Hsuan Wang, Chih-Fu Chang, Chao-Hsu Wu, Shih-Keng Huang, Hau Yuen Tan

Publication number: 20240266236Abstract: An electronic package module and the method for fabrication of the same are provided. The method for fabricating the electronic package module includes providing a circuit substrate. An interposer frame and a first electronic component are disposed on the circuit substrate, and a shielding material with an opening overlapping the electronic component is disposed on the interposer frame. Subsequently, with the shielding material being as a mask, the molding material is filled into through the opening, thereby forming the molding layer encapsulating the electronic component. After forming the molding layer, the shielding material is removed, so that an interface of the interposer frame is exposed. Therefore, the solder ball can be disposed on the interface of the interposer frame without further machining of the molding layer.Type: ApplicationFiled: July 19, 2023Publication date: August 8, 2024Inventors: LI-CHENG SHEN, Chao-Hsuan Wang
