Original Abstract Submitted

An electronic device such as a head-mounted display device may include an antenna that radiates through a cover. The antenna may have a ground and an antenna resonating element layered onto the cover. The ground may include conductive structures separated from the resonating element by a volume. The device may include a fan that conveys air through a vent in a chassis of the electronic device through a tunnel. The tunnel may be free from conductive material and may extend through the volume of the antenna. The fan may include blades enclosed within metal walls. A conductive mesh may be coupled between the metal walls and may separate the blades from the tunnel. This may serve to extend the volume of the antenna to also include at least some of the volume of the fan, thereby maximizing efficiency bandwidth of the antenna without sacrificing thermal dissipation by the fan.
