    Abstract: Wireless networks are vulnerable to identity-based attacks, including spoofing attacks, significantly impact the performance of networks. Conventionally, ensuring the identity of the communicator and detecting an adversarial presence is performed via cryptographic authentication. Unfortunately, full-scale authentication is not always desirable as ... Show More

    Abstract: The scattering radar cross section (RCS) and the resonant frequency problem of a superstrate loaded resistive rectangular microstrip patch which is printed on isotropic or uniaxial anisotropic substrate are investigated, where an accurate design based on the moment method technique is developed. The choice of two types of basis functions (entire do... Show More

    Abstract: Statistical properties of the error sequences produced by fading channels with memory have a strong influence over the performance of high layer protocols and error control codes. Finite State Markov Channel (FSMC) models can represent the temporal correlations of these sequences efficiently and accurately. This paper proposes a simple genetic algo... Show More

    Abstract: An array of coplanar capacitive coupled suspended microstrip antenna has been investigated to study the mutual coupling effect between its elements. Also, the work is extended to study the mutual coupling effect in Koch shaped coplanar capacitive coupled suspended fractal microstrip antenna. From the investigations it is observed that less coupling... Show More

    Abstract: In this paper, a coplanar capacitive coupled suspended microstrip antenna with reduced air gap (compact) for wireless applications is presented. Suspended microstrip antennas offer wide bandwidth due to the reduced effective dielectric constant and surface waves. However, air gap in the suspended configuration is the prime constraint in compact app... Show More

    Abstract: In this paper, a monopole antenna with triangular shaped patch based on coplanar waveguide (CPW)-feed is presented. The proposed antenna comprises a planar triangular patch element with a staircase ground which offers ultra wide bandwidth. The impedance bandwidth can be tuned by changing staircase shaped ground parameters (number of steps, step len... Show More
