The injection molded modified-material-based substrate is made of polyphenyl ether doped with a modified material, and the modified material has a relative permittivity of 2.65 and a density of 1.06 g/cm | 2021-12-02 |
20210376468 | ANTENNA DEVICE AND ELECTRONIC EQUIPMENT - An antenna device includes a radiating element, a coupling circuit, and a non-radiating resonant circuit. The coupling circuit includes first and second coupling elements, the first coupling element being connected between a feeder circuit and the radiating element, the second coupling element being coupled to the first coupling element. An end of the second coupling element is grounded, and another end of the second coupling element is connected to the non-radiating resonant circuit. A frequency characteristic of a return loss of the radiating element when seen from the feeder circuit is adjusted by a resonant frequency characteristic of the non-radiating resonant circuit. | 2021-12-02 |
20210376469 | HIGH GAIN AND LARGE BANDWIDTH ANTENNA INCORPORATING A BUILT-IN DIFFERENTIAL FEEDING SCHEME - An antenna and a base station including the antenna. The antenna includes a sub-array that includes first and second unit cells and a feed network. The first and second unit cells comprise first and second patches, respectively, having quadrilateral shapes. The feed network comprises a first transmission line terminating below first corners of the first and second patches, respectively; a second transmission line terminating below third corners of the first and second patches, respectively; a third transmission line terminating below a second corner of the first patch and a fourth corner of the second patch; and a fourth transmission line terminating below a fourth corner of the first patch and a second corner of the second patch. The first corners are opposite the third corners on the respective first and second patches and the second corners are opposite the fourth corners on the respective first and second patches. | 2021-12-02 |
