A performance comparison of smart antenna technology for wireless mobile computing terminals

The paper introduces two newly developed smart antennas, the ESPAR antenna and the ESMB antenna, for mobile wireless computing terminals and mobile stations. The configurations of these smart mobile terminal antennas at the operating frequency approximately over 2.4 GHz are illustrated and the applications of using these smart antennas at mobile computing terminals and mobile stations are proposed. The performance comparison of these smart antennas and the beam control circuits, and the beam-forming and selection algorithm is discussed.
