The slabs are chosen to be of equal optical thickness, and, hence, resembling the use of quarter-wavelength transformers in broadband matching re

A Quasi-Planar Wide Band Conical Antennacial property makes it irreplaceable in some modern applications, for instance, in portable or mobile communications requiring very wide-bandwidth channels or where continuous frequency coverage is needed. The prototype of the conical antenna has a threedimensional structure. It is mechanically diff

An Omnidirectional and Low-VSWR Ultra Wideband Antenna for a Frequency Band of 6 to 40 GHz Omnidirectional and low-VSWR requirements are essential for applications such as UWB channel sounding. The proposed antenna consists of a circular ground plane and a teardrop that is defined as a combination of a finite cone and a sphere inscribed inside the cone at the cone’s base. This antenna ca

An Approach to the Determination of the Phase Center of Vivaldi-Based UWB Antennabout several hundreds of nanoseconds, so even fine phase center drift will influence the phase of far field much and lead to the waveform dispersion in the time domain [2-3].if we recognize the far field which is radiated by the antenna as a sphere, then the phase center of antenna should be the cen

Application of UWB Antenna Descriptors to Antenna Performance Assessment defined by Federal Communications Commission (FCC). Several antenna performance descriptors, such as input impedance bandwidth, gain, beamwidth or effective antenna length, can face strong frequency dependence. In this context, the traditional narrowband approach to antenna design is no more approp
