Full-Wave Analysis of Microstrip Antennas in Three-Layered Spherical Media

Full-Wave Spectral Analysis of Resonant Characteristics and Radiation Patterns of High Tc Superconducting Circular and Annular Ring Microstrip Antennas

Microstrip Antennas

Microstrip antennas have been one of the niost innovative topics in antenna theory and design in recent years, and are increasingly finding application in a wide range of modern microwave systems. This paper begins with a brief overview of the basic characteristics of microstrip antennas, and then concentrates on the most significant developments in microstrip antenna technology that have been ...

One-Dimensional Wave Dispersion in Layered Media

Abstract. Homogenisation theory reveals that long one-dimensional waves propagating in a medium with spatially periodic wave speed can behave like dispersive waves in an appropriately homogenised medium. However the precise time and length scales over which this dispersive behaviour is a good approximation are not clear. This paper describes what happens in a specific case when the sound speed ...

Wave Propagation in Randomly Layered Media

An acoustical pulse propagating in a randomly layered slab and scattered by the random inhomogeneities generates a reeected signal and a transmitted pulse followed by its coda. In the regime of separation of scales (correlation length of the random inhomogeneities much smaller than typical wavelengths contained in the pulse much smaller than the large scale of the medium comparable to the size ...

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
