Abstract
Techniques for providing multi-antenna devices with increased antenna-to-antenna isolation as well as methods of operating and manufacturing the same are disclosed. A multi-antenna device may include a support structure, one or more radio devices coupled to a first antenna that is coupled to the support structure at a first location, a second antenna coupled to the support structure at a second location and communicatively coupled to the one or more radio devices, and a conductive structure coupled to the support structure so that it shifts an electric field null of the first antenna from an original location toward the second location during communications using the first antenna, thereby increasing isolation between the first antenna and the second antenna. The conductive structure may have a length of approximately one half of the wavelength (e.g., of 2.4 gigahertz or 5 gigahertz) of a frequency band used for the communications.
