The radiating patch was an E-shaped microstrip printed over a FR-4 substrate with relative dielectric constant of 4.3, and thickness of 3 mm. A microstrip line feeds this proposed antenna. To satisfy the UWB frequencies the length ground plane has been reduced. The finite ground plane is printed on the lower side of dielectric substrate. The modeling process and performance estimation of the designed antenna was achieved by using the electromagnetic simulator, Computer Simulation Technology (CST) Software. Simulation results indicate that the designed antenna has an effective bandwidth, for-10 dB, extending from approximately 3 GHz to more than 16 GHz, which covers the entire UWB band of 3.1 GHz to 10.6 GHz.

The notch band function was created by embedding a Π-slot within the radiator patch that has a small size (24 × 23) mm printed over a FR-4 substrate with relative dielectric constant of 4.3, and thickness of 1 mm. A microstrip line feeds the designed antenna. To satisfy the UWB frequencies the length ground plane has been reduced. The finite ground plane is printed on the lower side of dielectric substrate. The simulating process and performance estimation of the designed antenna was achieved by using the electromagnetic simulator, Computer Simulation Technology Software. Simulation results indicate that the designed antenna has an effective bandwidth, for |S_11 |≤-10 dB, extending from approximately (3.7 to 8) GHz and (8.8 to 10.75 GHz), with a switchable notch band performance in the (5.15 and 5.825 GHz).

the main advantages and disadvantages of the reconfigurable
antenna in addition to the most important applications that can
be used with the reconfiguring techniques, studying the
history of this technology with a brief literature survey is
explained. A detailed description for this technique with
examples and background information are specified,
reviewing the different reconfigurable antenna components,
which can be used in an antenna to adjust its construction
and functionality. These reconfigurable antenna techniques
are grouped with a different classification methods to

integration of micro-electro-mechanical structures
(RF-MEMS), varactors, PIN diodes, photoconductive
components, or on the function of smart materials like
