Plane-wave scattering-matrix theory of antennas and antenna-antenna interactions: formulation and applications

1 Antennas and Antenna Arrays

Antennas have become ubiquitous devices and occupy a salient position in wireless systems. Radio and TV as well as satellite and new generation mobile communications have experienced the largest growth among industry systems. The global wireless market continues to grow at breakneck speed and the strongest economic and social impact nowadays comes from cellular telephony, personal communication...

Virtual antenna array theory and applications

In this article we would like to present a physical basis of virtual antenna array method which is based on electrodynamic principle of field source equivalence. Also, here are formulae and numerical relations for field description errors for the field at the edges of physical and virtual antenna arrays It is also demonstrated that the virtual antenna array method helps increase radio emitters ...

Printed Wideband Antenna for Millimeter Wave Applications

Numerical Modeling and Experimental Study of Probe-Fed Rectangular Dielectric Resonator Antenna (RDRA) Supported by Finite Circular Ground Plane

Dielectric Resonator Antennas (DRAs) have received increased interest in recent years for their potential applications in microwave and millimeter wave communication systems. DRAs are normally used with the support of a ground plane. The radiation and impedance properties therefore depend not only on their physical dimensions and dielectric properties, but also on the size of the ground plane. ...

UWB Ring Filter and UWB Plane Antenna

UWB (U ̅ ltra-W ̅ ideB ̅ and) is a communications system that utilizes a bandwidth greater than 20% of the center frequency or at least 500MHz. It also uses extremely wide bandwidths ranging from hundreds of megahertz to several gigahertz. As shown in Fig.1, the output is less than the electromagnetic noise level of PCs; as such, conventionally used frequencies can be shared. The UWB provides the ...
