Abstract: An antenna structure includes a first signal connector and a second signal connector. The antenna structure further includes a cavity antenna defined by a set of planar walls. The cavity antenna is coupled to the first signal connector and configured to emit a field polarized linearly in a first direction when driven by a signal at the first signal connector. The antenna structure further includes a dipole antenna defined by a pair of arms that are integrated with a wall of the cavity antenna. The dipole antenna is coupled to the second signal connector and configured to a field polarized linearly in a second direction offset from the first direction when driven by a signal at the second signal connector.

Abstract: An antenna structure includes a first antenna element connected to a first port, and a second antenna element connected to a second port. The antenna structure is operable to simultaneously transceive: a first signal via electric or magnetic current flow through the first antenna element in a symmetrically excited mode in which current flows symmetrically through the first antenna element and/or an asymmetrically excited mode in which current flows asymmetrically through the first antenna element, the first antenna element resonates at a first resonant frequency; and a second signal via electric or magnetic current flow through the second antenna element in a symmetrically excited mode in which current flows symmetrically through the second antenna element and/or an asymmetrically excited mode in which current flows asymmetrically through the second antenna element, the second antenna element resonates at a second resonant frequency.

Abstract: A method includes separately collecting, by a terminal, a transmit power of the terminal at different time points in a second duration after a first duration from a power-on moment to obtain a plurality of transmit powers, calculating an average transmit power of the transmit powers, determining based on the average transmit power, a specific absorption rate (SAR) corresponding to the average transmit power, and decreasing a transmit power of the terminal after the second duration when the terminal determines that the SAR is greater than a preset threshold.

Abstract: A single feed antenna design is conducted on a radiator of a specific shape (for example, a strip radiator or a slot radiator) to excite a plurality of antenna modes. For example, performing a feed design on a strip radiator may excite a CM wire antenna mode and a DM wire antenna mode. For another example, performing a feed design on a slot radiator may feed a CM slot antenna mode and a DM slot antenna mode. The antenna design may be used to cover a plurality of frequency bands when an antenna is miniaturized.

Abstract: An antenna structure comprising: a first port; a second port; and a single radiator connected to both the first and second ports, the single radiator being operable to simultaneously transceive in: a symmetrical excited mode in which current flows symmetrically through the single radiator to or from the first port, thereby causing the single radiator to resonate at a first resonant frequency; and an asymmetrical excited mode in which current flows asymmetrically through the single radiator to or from the second port, thereby causing the single radiator to resonate at a second resonant frequency. The single radiator comprises: a first element, a second element, and arm connectors connecting the first element to the second element. The first element being elongate and linear. The second element being elongate, linear, and parallel to the first element.
