Antenna placement
View Patent ↗Antenna placement techniques are described. In one or more embodiments, a computing device includes an antenna suite having multiple different kinds of antennas. An antenna zone for the antenna suite may be established along a particular edge of the computing device. Non-interfering materials (e.g., RF transparent material) may be used within the antenna zone and other materials (e.g., metal) may be employed for other regions of the device. The multiple different kinds of antennas in the antenna suite may then be disposed within the established antenna zone. The antennas may be placed to minimize interference between antennas and/or achieve performance objective for the suite of antennas. In one approach, a suite of five antennas may be placed along a top edge of a computing device in a landscape orientation.
