Ultra-Wideband Array Antennas

open access: yes, 2014
Wireless communication has become an indispensable part of modern life. One of the mostimportant components of wireless communication systems are antennas, termed as "eyes" and "ears" of communication systems. A printed antenna, one of the most commercial antennas, is widely used for civil and military applications, i.e., for communication systems ...

Hemispheric ultra-wideband antenna. [PDF]

open access: yes, 2006
This report begins with a review of reduced size ultra-wideband (UWB) antennas and the peculiar problems that arise when building a UWB antenna. It then gives a description of a new type of UWB antenna that resolves these problems. This antenna, dubbed the hemispheric conical antenna, is similar to a conventional conical antenna in that it uses the ...
