Abstract: In an antenna design, a metal frame of an electronic device and a printed circuit board (PCB) form a slot antenna radiator, where two common mode (CM) slot antenna modes of the slot antenna radiator are excited through anti-symmetrical feeding, so that when dual resonances and wideband coverage are implemented, specific absorption ratio (SAR) values in the two CM slot antenna modes are close.

Abstract: An antenna assembly, an apparatus having the antenna assembly, and a method of manufacturing the antenna assembly are disclosed. Antenna performance in, e.g., mobile devices is improved via an antenna assembly which allows wide-angle beam scanning across a wide frequency bandwidth. Wide beam coverage may in turn contribute to improving multi-surface spherical beam coverage, such as in broadside direction and endfire direction, and to reducing the amount of needed antenna modules. A tightly-coupled dipole array exhibits wide operating frequency bandwidth characteristics.
