“…In terms of the control time, the controllers are classified with continuous control and discontinuous control. Compared with the continuous control, the discontinuous control including the impulsive control [20,21] and the intermittent control [22,23] has attracted much more attention, and it is very effective, practical, and applicable in many areas, especially in secure communication [24].…”

This paper addresses the exponential stability problem for a class of delayed bidirectional associative memory (BAM) neural networks with delays. A sliding intermittent controller which takes the advantages of the periodically intermittent control idea and the impulsive control scheme is proposed and employed to the delayed BAM system. With the adjustable parameter taking different particular values, such a sliding intermittent control method can comprise several kinds of control schemes as special cases, such as the continuous feedback control, the impulsive control, the periodically intermittent control, and the semi-impulsive control. By using analysis techniques and the Lyapunov function methods, some sufficient criteria are derived for the closed-loop delayed BAM neural networks to be globally exponentially stable. Finally, two illustrative examples are given to show the effectiveness of the proposed control scheme and the obtained theoretical results.

This article presents a dual‐band/dual‐polarized microstrip patch antenna.For a dual‐band retrodirective array system, the dual‐band/dual‐polarized microstrip patch antenna operating at 11 and 12.2 GHz is designed and tested. The antenna consists of one rectangular microstrip patch and a square ring outside of the patch. Two different feeding locations are used for vertical and horizontal polarizations. The vertical polarization is used for a receiving mode and the horizontal polarization for a transmitting mode. The antenna shows a measured gain of 5.2 and 6.8 dBi at 10.9 and 12.2 GHz. The isolation between the two feeding ports is measured to be greater than 15 dB at each center frequency. © 2012 Wiley Periodicals, Inc.

Abstract-In this paper, a fractal dual-polarized aperture-coupled microstrip antenna is presented. The proposed antenna adopts 1st Minkowski fractal patch and is fed by the aperture-coupled structure with H-shaped and H-shaped loaded capacitance.The size of Minkowski fractal patch is reduced by 20% compared with a square patch. Results show that the T/R isolation is better than 35 dB, improved by 2 dB compared with the double H-shaped slots. The gain is more than 8 dB, and the front-back ratio is greater than 20 dB in the operating frequency range. Both simulated and experimental results are in good agreement.
