Abstract
A smart antenna with an adjustable radiation pattern is described. A plurality of slot antennas are formed at a metal layer which is grounded, wherein openings of the slot antennas point to different directions. One surface of an insulated layer is covered by the metal layer. A coaxial feeding structure is provided through the insulated layer. A plurality of microstrip lines are formed at the other surface of the insulated layer and can feed the radio frequency signals to the slot antennas, respectively. Pluralities of switches are connected to each microstrip line and the coaxial feeding structure. A plurality of bias circuits are electrically connected to each switch, respectively, to control the status of the switch and adjust the operation statuses of the slot antennas individually to form an adjustable radiation pattern.
