Abstract
An ultra wideband antenna with a circular structure that has a modified ground plane is presented in
this article. By adding a U-slot in the conductor side of the circular patch, an ultra wideband antenna
with a rejection band can be achieved. The U-slot parameters; length, width and gap are used to
control the center frequency of the rejection band. Simulation for the regular circular patch shows that,
the antenna impedance bandwidth covers the frequency range of 3.1–10.6 GHz. With controlling the
U-slot parameters, the rejection band can cover the range from 5.4-6.8 GHz. The performance of the
proposed antenna with U-slot and the regular circular patch antenna were measured and compared
with the simulated results, good agreements were found.
