摘要： An electronic device includes a multi-frequency antenna. The multi-frequency antenna includes a ground portion, a support body, a radiation portion, and a strap. The ground portion defines a gap, and two grooves communicating with the gap and located at opposite ends of the gap. The radiation portion resists against a sidewall bounding the gap, and is connected to the strap. The radiation portion is accommodated in the gap and substantially coplanar with the ground portion. The radiation portion defines a slot. The support body is located in the gap and on the radiation portion, to support the strap.

A third ground sheet is arranged between the two circuit layers. A differential pair includes a transmission line arranged between the first and third ground sheets and a transmission line arranged between the second and third ground sheets.

摘要： A computing device and a method determines port relationships of a differential transmission line of a circuit board according to an original scattering parameters file, which records scattering parameter values measured from ports of the differential transmission line under different signal frequencies. The computing device generates a new scattering parameters file matching a scattering parameters model predefined for the differential transmission line according to the determined port relationships. Design of the differential transmission line is analyzed to determine if the differential transmission line is qualified according to the new scattering parameters file and the scattering parameters model.

摘要： An enclosure of an electronic device includes a ventilation plate. The ventilation plate is a grid including a number of crisscrossed connection bars and a number of through holes defined by the connection bars. A tab is formed at each of the connection bars bounding each of the through holes. The tabs are substantially angled from a plane of the grid to elongate a path electromagnetic signals must travel to pass through the ventilation plate. The enclosure with the shields can shield the electronic device from EMI.

摘要： A printed circuit board includes a number of signal layers, a number of ground layers, a first transmission line, a second transmission line, a first via, and a second via. The first transmission is located on one of the number of signal layers. The second transmission line is located on another of the number of signal layers. The first and second vias pass through the printed circuit board. The first via is electrically coupled to the first and second transmission lines, and is isolated from the number of ground layers. The second via is electrically coupled to one or more of the number of ground layers, and is isolated from the other of the number of ground layers to increase an inductance, thus compensating capacitive nature of an open stub and improving signal integrity.
