We propose an accurate analytical model for a circularly polarized antenna comprising a normally magnetized, grounded ferrite disk with a metalized top surface. The antenna is assumed to be excited by a conventional current probe. In the case of a thin ferrite disk, the electromagnetic fields of the dominant mode of the antenna do not vary in the direction normal to the disk. However, with increasing...
The necessity to use a great bandwidth in communication industries led to a change of the shape of the monopole antennas and use of a flat rather than a bar as radiator. This type of antenna was proposed for the first time in 1958 by Mr. B.J. Lamberty in the form of a rectangular plate. from then on, other similar antennas were presented in the shape of circular, elliptical, and trapezoidal discs...
Ultra-high speed wireless systems have gained an increasing attention in recent years. The development of multi Gbps wireless link for personal wireless networks (WPAN) is linked to several constituent systems,each autonomous, yet interconnected. This paper looks into the emergence of a new technology within a system of systems perspective. One of the characteristics of System of Systems is emergence...
