This paper investigates the design and practical implementation of a Super Wide Band
(SWB) antenna along with the application of fundamental bandwidth limitation theory of …

A compact, ultrawideband (UWB) antenna occupying a cylindrical volume and providing
omnidirectional monopole-like radiation is introduced. The antenna consists of two closely …

A compact, ultrawideband (UWB) antenna with an extremely low profile is presented. The
antenna has consistent monopolelike radiation characteristics over approximately an 8.5: 1 …

Ultra wideband technology has shown great promise for providing high-quality location
estimation, even in complex indoor multipath environments, but existing ultra wideband …

We present an electrically small, low-profile, ultrawideband (UWB) antenna with monopole-
like radiation characteristics. The antenna is composed of a monopole bow-tie antenna …

Beginning with a brief overview of the history of lower bounds on the quality factor Q of
antennas and the fundamental relationships between the impedance, bandwidth, and Q of …

By tuning with dispersive permittivity or permeability, the quality factors and thus the Chu
lower bound for lossy magnetic-or electric-dipole antennas at isolated resonances or …

After a brief history of the development of quality factor, useful expressions are derived for
the robust Qz (w) quality factor that accurately determines the VSWR input-impedance …

The fundamental bandwidth limitation theory of small antennas and their applications to
Super Wide Band (SWB) antenna designs are investigated in this paper. Firstly, a circular …

The ultra wideband UWB antenna shape determines both the lowest operating frequency
and Q-factor ratio. For electrically small antennas, the quasi-static antenna design algorithm …
