Patent attributes
An electronic device is described. This electronic device includes: an interface circuit; and an antenna having a radiator and multiple pairs of reflectors arranged along different axes passing through the radiator in a horizontal plane. A given pair of reflectors includes reflectors on opposite sides of the radiator and along a given axis. During operation, the interface circuit provides control signals to switching elements that selectively electrically couple one or more of the reflectors in the pairs of reflectors to ground, where the one or more of the reflectors modify an antenna radiation pattern of the radiator. Then, the interface circuit communicates, via the antenna, a packet or a frame with a second electronic device, where the communication involves transmitting or receiving wireless signals corresponding to the packet or the frame.
