In this thesis, the design of printed monopole antenna for dual band wireless communication applications is introduced.

The design approach has been essentially based on the ultra-wide band printed monopole antenna structure.

The resonant behavior of any ultra-wide band antenna is composed of a large number of resonant bands coupled to form the resulting response.

These resonant bands have been attributed to the different parts of the antenna structure.

This can be monitored when observing the current distributions at the surface of antenna structure at these bands.

In this context, the dual band behavior of the proposed antenna can be extracted from UWB one through the modifications on the different parts of the antenna structure with the aid of the related current distribution.

It has been found that the radiating element and the ground plane are the most effective parameters to achieve this aim.

The resulting dual band antenna has been formed to possess adequate dual band response in addition to reasonable gain and radiation characteristics.

All the presented antennas have been modeled using the same substrate which is (FR4) with (1.6) mm thickness, and (4.6) relative dielectric constant and have been fed with a (50) Ω coplanar wave guide (CPW) transmission line.

Modeling and performance evaluation of the different antennas presented in this thesis have been carried out using the Computer Simulation Technique (CST).

Furthermore, it has been found that applying the fractal geometry on the radiating element, results in an enhanced resonance of the dual band antenna and a better coupling of the obtained resonating bands.
