Abstract: In an example, an electronic device may include a housing and a display panel disposed in the housing. Further, the electronic device may include an input assembly disposed in the housing abutting a side of the display panel. The input assembly may include a printed circuit board (PCB), a sensor disposed on the PCB, and a first keep-out zone defined on the PCB on a side of the sensor. Further, the electronic device may include an antenna disposed in the first keep-out zone of the PCB.

Abstract: In some examples, an antenna assembly includes a driven antenna element to communicate a signal over an antenna feed line, and a printed circuit including an electrically conductive pattern that is placed adjacent the driven antenna element. The printed circuit including the electrically conductive pattern provides a parasitic antenna element for the driven antenna element.

Abstract: The present disclosure relates to a compact antenna system within a dielectric housing of an electronic device, capable of achieving improved reflection performance. The antenna system includes a ground plane and an antenna PCB. An antenna microstrip feed on a side of the antenna PCB comprises a first part of a radiating antenna element. The antenna PCB is connected to the ground plane by a central conductor of a coaxial cable which forms a ground path. An outer conductor of the coaxial cable carries RF signals to the antenna PCB, allowing the RF signals to freely radiate along a length of the coaxial cable and acting as a second part of the radiating antenna element. The coaxial cable does not interfere with, and can even enhance a radiation pattern of the antenna microstrip feed.
