1. An ultra-wide band dipole antenna assembly for transmitting or receiving electromagnetic signals, the ultra-wide band dipole antenna assembly comprising:
a first quarter wavelength conductor element with a first end;
a second quarter wavelength conductor element comprising a main body with a first collar and a second collar extending from the main body toward the first end of the first quarter wavelength conductor element; and
a coplanar strip line connected on a first end to the first quarter wavelength conductor element with a first slot between a second end of the coplanar strip line and the second quarter wavelength conductor element;
wherein the first quarter wavelength conductor element, the second quarter wavelength conductor element with first collar and second collar, and the coplanar strip line and the first slot form a coplanar waveguide feeding network;
wherein the ultra-wide band dipole antenna assembly operates in a frequency band range from 600-960 MegaHertz (MHz) and 1400-6000 MHz.
